Does Epoxy interact with bondo?

[C_Brice]

Hello all again. Have a question, not a boat question but along the same lines.

My lastest project is a small camper. Similier to a teardrop but with a more modern design that I came up with. It's all built, sanded and all the screw holes are filled with Bondo. Now I'm ready for the top coat. I have some Raka Epoxy and am thinking of using it on the exterior but I am worried that it will not play well with the bondo I used on the screw holes.

If the Exopy won't play well with the bondo I'm gonna have to use automotive poly resin and I know how you all feel about the poly so we don't need to go there :lol:

Thanks for the help,
Chris

Until you get a scientific or technically qualified answer, try a small sample.

As it's drying, Googleize bondo and call them up. Also try Googleizing and calling West Systems and System 3.

For you camper application, it should do just fine. Let the bondo fully cure first, sand the surface of it with around 100 grit, then apply the epoxy.

Doing a test on a small area or scrap board with bondo on it wouldn't be a bad idea.
