Step 1: Bear upon Up Kits

Duplicolor has simple paint touch on-upward kits that y'all can buy at your local auto parts store, and many dealerships can sell yous a paint pen in your car's exact mill colour. You tin also buy more than involved touch-up kits and supplies online. For case, the kit we tested from PaintScratch came with primer, clearcoat, pigment thinner, a bottle of rubbing compound, and color-matched paint.

PaintScratch used data in the car's Vehicle Identification Number—the long combo of letters and numbers commonly referred to as a VIN—to verify the correct shade of paint, which is a pretty common practise. These kits are more than expensive and have more steps, but ultimately provide a better, longer lasting event.

Pace 2: Bank check the Door

You need to identify the paint lawmaking for your vehicle to ensure y'all are getting the correct shade of pigment, which is easy to detect if your car has never been repainted a different color. On most cars built since 1983, this information may be found on a sticker on your driver's door or door jamb. To be admittedly sure of a match, the paint vendor may too need the VIN, which can exist plant on that aforementioned door sticker or on the VIN plate on your dash.

If your auto has been repainted a unlike color in its lifetime, you lot'll obviously need to discover that color instead. Hopefully that colour is listed somewhere in the records for the car, but if not, you'll likely want to shop for paint in person to make sure you're getting a proficient lucifer.

Step 3: Become Shopping

Preparation is the key to getting practiced results. Yous'll need very fine g-dust, 3M Wetordry sandpaper, various arts and crafts sticks, cotton swabs, thin-tip splinter tweezers, glue dots, and various newspaper punches. Everything except the tweezers came from a local craft store.

Pace iv: Making Your Sanders

Most off-the-shelf sanding tools would damage a lot of perfectly fine pigment around the chip, so we'll need to make our own miniature sanders. Utilize the punches to cut out pocket-size sandpaper circles and mucilage them to the craft sticks and dowels. Don't be agape to think outside the box at the craft shop, either. We found a $one.99 bag of wooden axles with nice rounded ends that worked well on larger chips.

Step five: Launder the Machine

Start, launder the car with warm soapy water, rinse thoroughly, and let it dry out. You want to exist certain the machine is completely complimentary of clay in order to become a smooth repair.

Step 6: Remove Built Up Waxes and Coatings

Next, remove any wax, grease, and silicone that would prevent fresh paint from adhering to the surface of your auto. PPG Acryli-Make clean is one such solvent that'due south prophylactic for this, and can be found at professional person body store stores and some larger auto parts stores.

Step 7: Fill Modest Fries

For very small chips, nosotros recommend using a paint pen. The small tip on the Duplicolor paint pen was like shooting fish in a barrel to command and made filling the divot piece of cake. Use plenty pigment that information technology rises barely above the surface. This allows for shrinkage during drying, and any slight backlog tin be wet sanded downwards and and so rubbed smooth.

Well-nigh stone chips are probably on your hood's leading edge. To prevent the pigment from running before it dries, you tin can lift the hood until the bit is horizontal to the basis to keep the pigment in its place fifty-fifty while wet.

If these are the only chips your car has, yous're lucky! Otherwise, read on.

Step 8: Make clean Upwardly Medium Chips

If your remaining chips are larger, skip ahead to Step 11. For medium size fries, we'll need to use the brush applicator. Before your start brushing on anything, clean out any loose debris and pigment from inside the chip with your tweezers.

Pace 9: Apply the Primer

Utilise the primer with the applicator castor as directed. Information technology'due south important to read and follow the instructions, every bit these can vary betwixt paint vendors. Pay close attention to how long information technology will accept for the pigment to dry for each layer, exist information technology primer, pigment, or clearcoat. Working over wet paint could leave rough spots, bubbles or holes in the finish, which wouldn't exercise every bit much to protect or raise the appearance of your auto.

Step 10: Apply the Paint

Subsequently the primer cures, utilise the paint. At this point, the filled chip on our test automobile didn't look likewise bad from six anxiety abroad. Wet sanding, applying the clearcoat, moisture sanding again, and then rubbing the chip smooth improved the await of the repair considerably. Later that, the repair looked groovy from about three feet away, depending on your eyesight and the amount of sunlight. You'll have to decide how much work yous desire to invest hither.

Footstep 11: Clean Up Large Fries

The rest of these steps are for fixing large paint chips, which are the ones most probable to expose the car's bare metal to the elements and atomic number 82 to further damage. On larger chips and those that already have a rust colony growing, employ the splinter tweezers or a fine dental option to flake off any loose paint.

Y'all must be very conscientious because you can hands plow a small chip into a large one if you loosen up whatever paint that isn't loose already. Even so, if you don't remove the loose paint, the paint will somewhen flake off on its ain and spoil the repair.

Pace 12: Remove Rust

Swab CLR, Ultra One's Safest Rust Remover, or an equivalent rust remover into the bit to dissolve and remove rust. Keep doing this until your swab comes upward clean. Adjacent, rinse the rust remover out of the bit with isopropyl booze. If y'all don't remove all the rust, the paint won't properly adhere to the motorcar and rust will spread under the pigment.

Step 13: Sand the Edges

Carefully dry-sand the edges of the chip until they await smoother and more than rounded off. You don't want any sharp edges that will brand the repair look more obvious. The curved shape of the wooden axle end made it the ideal tool for this. H2o will restart the rust process, so do this sanding dry. The 3M Wetordry sandpaper clogs quickly when used for dry sanding, but the adhesive dots make changing sanding circles easy.

Footstep 14: Apply Leverage

At present is the time to whip out a flat craft stick to use with a minor circumvolve of sandpaper. Using the edge of the apartment wood sanding stick will utilize more than leverage when sanding the flake and the expanse around it, but don't sand too far outward or y'all'll sand through the clearcoat and brand the spot more than noticeable.

You desire to taper the edges of the chip so the boundaries of your repair are less noticeable. Brand sure you wipe or blow off the remnants of your sanding job earlier moving on to the adjacent steps.

Step 15: Apply the Primer

Carefully utilise the primer from the center outward. You don't want to become beyond the edge of the chip. If y'all do, utilize a cotton swab moistened with lacquer thinner to quickly wipe up the backlog primer. Proceed all of your painting supplies close at manus on a small table. Y'all don't desire to have to go searching and fumbling later on a mistake equally the paint doesn't stay liquid for long.

Step xvi: Permit the Primer Dry

Let the primer dry out to full cure, which could take a while depending on temperature and humidity. Be sure to follow the directions that came with your pigment or repair kit, as they tin suggest you on the number of coats you'll need for primer, paint, and clearcoat besides equally the amount of time each layer needs to dry. Budget enough time to let the primer completely dry before roofing it with paint.

Step 17: Wet Sanding

Once the primer dries, y'all tin wet sand it to set up the primer base of operations for paint. Once again, don't sand as well far from the center of the fleck or y'all volition sand through the surrounding clearcoat. Sanding through the clearcoat is especially noticeable if your machine has dark or metal paint.

We recommend using a stronger, water resistant adhesive for these wet sanding sticks. It's non- removable, but you won't need to change sandpaper equally often when wet sanding. We pre-made iii sticks with sand newspaper circles on each stop for a total of 6 moisture sanders.

Pace 18: Steady Hands

Painting a chip this big with a castor will never requite you a factory stop, but you tin can at least seal the metal back up and make it look nice from further away. Steady easily and a small corporeality of paint on the castor worked best. Have information technology from your local manicurist: Thin, smooth coats are best when working with multiple layers.

Double- and triple-check that your primer is dry before you lot offset this. While testing the PaintScratch kit, we made the error of painting too before long after a second coat of primer. The solvent in the pigment began to deliquesce the primer and thin swirls of grayness mixed into the white.

Step 19: Add Clearcoat

Keep wet sanding the painted spot until it is smooth. Adjacent, brush on the supplied clearcoat. Similar the paint, clearcoat is lacquer based, sparse, and it dries fast.

In this picture, you can encounter the boundary betwixt the new lacquer and the original enamel. That happens when the edges of your repair aren't sanded down plenty to taper into the scrap. Be conscientious with your preparation piece of work, and become the bit as shine equally possible before you movement on to the adjacent step. If you're happy with how your repair looks, though, you can skip ahead to Stride 21.

Step xx: Repair Your Repairs

If your repair didn't plough out well the first time, don't fret—at that place are ways to salvage information technology. Later on your previous attempt dries, sand the spot back down to the primer with a 360-grit 3M Wetordry sandpaper. This time, information technology's imperative to stay within the repair zone, so you probably want to trim your sandpaper circumvolve to sit even with the radius of your stick. Wipe off any actress dust or moisture, then repaint the spot. Wet sand the spot with yard-grit sandpaper in one case the paint is completely dry. Add your clearcoat, and so moisture sand once more. This tedious procedure slowly built up new layers of paint to sit down even with the original surface.

Step 21: Use Rubbing Compound

One time the repair is flush with the rest of the paint, take some rubbing chemical compound and shine the area with a clean cotton cloth. Launder the area with soapy water to clean off all the rubbing compound, rinse thoroughly, and permit it dry. Allow the repair continue to cure for about a week before waxing your car.

Step 22: All Done

All done! Hither is the same surface area where the large chip was, without whatsoever photoshopping. It won't fool a concours guess, but information technology is a big improvement.

Of the products nosotros tested, the Duplicolor paint pen was the easiest to employ on small fries. The color didn't match besides equally the VIN-matched paint but it was a deal at around $10. The $75.65 kit from PaintScratch was better for larger chips but required a tremendous amount of sweat disinterestedness and extra materials, plus the learning curve was steep. It cost Paul about $150 in materials and about 20 hours of work to go his paint chips fixed at habitation, compared to a quote of about $300 to have his hood repainted.

Unless time is of the essence, simple pigment scrap repair is an easy plenty chore to try yourself. Take intendance of chips as soon as you can! You're not only saving money on a full repaint, just on future repairs. Your paint is your motorcar'southward starting time line of defense from the elements, after all. Care for information technology as such.
