Tools & Materials needed:

- Touchup or color matched paint - google touch up paint
- Clearcoat (optional) - auto parts store
- Primer - auto parts store
- Rubbing Alcohol - cvs
- Small sanding block or piece of wood
- 1200, 1500, 2000 grit automotive sandpaper - auto body or parts store
- Small bowl
- Compound – 1000 grit remover, 2000 grit remover (optional) - some auto parts store has them or auto body has all this
- Orbital Buffer (optional – but makes it easier) - look online
- Paper cup
- Toothpicks

1.) Start by cleaning the chip and surrounding area with rubbing alcohol to get rid of grease, dirt, etc.

2.) Depending on what kind of paint you have you will need a paper cup to hold some. Since I have a spray can, I sprayed some in the cup. If you have touch up paint in a little bottle you don’t need a cup :chuckles:

3.) Break the toothpick so it doesn’t have a sharp point anymore and dip it in the paint and let it drip into the chip. You can do the same for this if you have a brush for the touch up paint bottle.

4.) You will want to repeat this process several times so you form the paint above the chip like in the picture below: **Note, if you want to use clear coat, use clear coat before the paint *blob* goes above the surrounding surface, and just build up clear coat to sand off like you would with just building up paint. The clear coat will be what you sand off and not the paint so make sure you only do a few coats of paint and the rest clear if you desire this.

5.) If you are worried about getting paint everywhere, you can tape around each chip:

6.) Yah I have a lot of small chips as you can see.

7.) Next comes the sanding. Make sure you soak your automotive sandpaper for 24 hours in water prior to using.

8.) Take your block of wood and wrap the sandpaper around it shown here:

9.) You will want to sand in a back and forth movement until the “blob” of paint is no longer visible and the surface is smooth again. Take your time, as this process is time consuming. Keep the surface wet, and dip your sandpaper in water frequently to clean off paint and to keep it wet.

**See picture above, I didn’t put enough paint so you can still see the chip after sanding

10.) At this stage you can either apply clear coat to the chip area and re-sand or just buff the scratches out which I did because I don’t have patience.

11.) If you buff by hand, apply compound to a micro fiber and rub back and forth until the surface is glossy again.

12.) And there you have it, a complete how to repaint paint chip guide. Some things I didn’t use was primer. If the chip is down to bare metal, you would use the same process as dipping the tooth pick in primer and putting a drop on the chip so the paint will stick.

13.) Put a nice coat a wax on after you buff since it will remove all wax that you “buff” off the car.

Good luck all, I hope this helps.

Thanks to Design for this:

Here are a few things to help you out. :smokin:

1. Paint prep pen: Great for smaller chips where you don't want to scratch the surrounding paint. They come in a variety of grades.

2. Syringe: I think you need to be 18+ to get this... but it works great for thin, hairline scratches. Fill the syringe with touchup paint of choice then apply a thin, even coat across the affected area.

3. Patience, patience, patience: Touching up paint the right way can take several days. Not only do you need to wait 24 hrs after you apply the primer, but you also have to do the same for each layer of touch-up paint you apply. For deep chips, you may have to apply 6-7 coats to effectively match the top surface area. The top layer should be barely above the surrounding area, so when you sand it down it will closely match in thickness.

Hope this helps.

I would only recommend this to those who might be willing to much up their paint. Personally I would rather use a paint pen then attempt this complicated yet delicate process. One mistake and it will look 10x worse.

If someone can do this, awesome. Much cheaper than repainting your entire hood.

Agree. I'd prolly just use a pain pen or something b/c a week after this process, i'll have like 5 more chips.

Just sharing thoughts.

I search both forums and found a product called "Langka".

Really easy to use and found it worked out really well. Give it a try?

Its around $50...but well worth the money...I think. Works really well...but agreed that you should do it when its warmer, I tried to do a couple small chips last week and it just not the same.
