Acrylic enamel cure
I had some scratches and chips in my paint. I touched it upwith a small artist brush. I thinned out the paint with reducer. Since I did not use a catalyst how long do I have wait to color sand? I live in So. Calif.

Re: Acrylic enamel cure
acrylic enamel with out a catalyst is like oil based enamel, it takes for ever to dry, in hot sun you might be able to start to do some work with it in 2 to 3 weeks, it depends on who made the paint, and the reducer you used, fast medium or slow, how many coats applied, it will take awhile, go slow, test in an out of site place, if its not cured it will gum up

Re: Acrylic enamel cure
I've used Acrylic enamel for many years with great results. If the directions call for hardener to spray, use it to touch up nicks and scratches.

When hardener additives first came along, they were added to the solvent based acrylic enamels. Hardener added in changed the paint formula from a straight acrylic enamel to an acrylic urethane formula. With water based acrylics, it's not so easy to figure out what the hardener is as it used to be so it's even more important to follow manufacturers instructions with it. Most folks use base coat/clear coat now so they aren't as popular as they used to be and therefor not supported as well as they used to be. I like the PPG Concept acrylic urethane. The rest of their products are an unknown to me since things have changed in the paint world so much over the past 20 years. They are talking about doing away with it so what to do next?
