Pick up a matching single stage paint that isn't lacquer based. ( Dries too quickly. ) Get a very tiny brush from a hobby store. Also some naptha. Don't thin the paint. As you want the paint to have some body to it. As you don't want the paint to flow out of the chip. Place small amount of paint in the chip so that the paint sticks up above the surface you're fixing. Let that fresh paint set up for about 15 minutes. Temp/ humidity will affect the wait time. Get a small part of a paper towel very wet with naptha. Gently, and slowly whip the fresh paint so that the thinner will dissolve the high points away first. The key is to let the thinner soften the highest point first. It's kind of like sanding off the high spots. With some practice, and care. The chip will be completely gone with no signs the it was ever there.Bob Dunahugh78 Royale

ok, dumb question: do you mix the activator with the single stage paint first? Or just use the paint straight out of the can? I've noticed the single stage will set up eventually even without the activator, just takes longer and I'm guessing will not be as durable.

thanks,
Karen

Because the paint won't ever get hard enough to wet sand without the hardener. I did about the same approach when I freshened our paint year before last:

http://gmc.mybirdfeeder.net/GMCforum/index.php?t=msg&goto=261900&rid=2555&srch=Paint+repair#msg_261900

I used primer to fill the dings and then painted over it. I could have done like Bob described and just built up the color. I used Acrylic enamel with hardener. When you add hardener to acrylic enamel it becomes urethane but costs less. Either will work fine.

I'm not sure you can even get hardened paint products on the left coast any more. I have no idea how to use waterborne products.

I used non hardened acrylic. Since I didn't put any thinner in the paint. It got hard enough, that I could work it down with the paper towel with thinner on the towel in about 15 minutes. And get the surface flat, and smooth. As to durability. I was only doing chips, and small scratches. It'll look great for along time. If you want. Put in some hardener.

Pete. The paint brand that I used was Nason acrylic enamel. Formerly DuPont. The Royale color is from a 2011 Mercedes ( light ivory ) with a minor tint added. I'd have to look at the can for the tint code.Bob Dunahugh 319-521-4891 Iowa

Summit Racing sells all kinds of paints, and some of it can even be shipped here to California.
Just have to stick with the "low VOC" versions. I painted our coach with their Single Stage Acrylic Urethane.
Looked pretty decent (at least at 20' or so) but then we had a huge windstorm that caused part of
the cheesy shelter it's under to act like a battering ram on the right quarter of the nose.
Now I have a bunch of ugly dings to fix...

thanks,
