Jig Man Posted February 18, 2021 Report Share Posted February 18, 2021 I’ve read everything that I can find and guys were having mixed results using high temp paint as a sealer. I am thinking a light coat of Bondo fiberglass resin might work. I have sealed some homemade molds for a friend and it worked but I have never tried it on a metal mold. Have any of you used it?

mark poulson Posted February 18, 2021 Report Share Posted February 18, 2021 I would be afraid it would fill in some of the details too much. Quote Link to comment Share on other sites More sharing options...
Les Young Posted February 18, 2021 Report Share Posted February 18, 2021 Whatever you do don’t use high heat krypton like you put on a stove because it won’t set up. It may if you baked it, but I painted some last summer while it was very hot & layed them in the sun to dry. I ended up having to get aircraft stripper & strip the paint off because I painted all I had after watching videos on it & it just never cured right. Then I shot a couple shots of old light colored left over plastic to get them good & clean. I’ll just use them like they are from now on. 1 Quote Link to comment Share on other sites More sharing options...
