    MAX GPE epoxy gel coat is available at a good price and seems easy to use. Has a long pot life. A Google search yields nothing. This site, since a search does not acknowledge 3-character terms, yields no results.

    Thanks...Alan

    What do you plan to use it for?

    It appears to be just a normal epoxy with white pigment added.

    It even warns about needing a coating for UV protection.

    Thanks for replying.

    I'm looking for a exterior solid colored white gel coat I can tint for a canoe infusion project (epoxy). I did read about it's lack of UV protection. I thought it might be more abrasion resistant than typical epoxy.

    I didn't see anywhere where it said it was for in-mold use. Epoxies tend to sag and run when sprayed on a mold surface. And spraying epoxy is a bit risky.

    There are epoxy compatible gel coats that do exactly what you want and are easy to get. Plus they're UV stable.

    Thanks for the feedback. I was going to brush it. I think I'm going to reverse course and use a polyester gel coat and infuse with vinylester. I have asked this question to a potential supplier. Can I infuse vinylester over a polyester gel coat that is still tacky?

    You need to wait until it doesn't come off on your finger, sooner will cause problems.

    Brushing works, but like anything else, its a learned skill with gel coat.
