SlowFISH Posted May 19, 2018 Report Share Posted May 19, 2018 Hey guys.... I have a resin mold I tried to coat in Hi-Temp paint (Duplicolor High Heat Ceramic) to give a nice smooth finish.... first shot and this stuff reacted with the plastisol and melted... basically locking the mold shut - after i pry'd it open - half of it was on/in the bait- the rest bubbling, tacky and could be wiped off the mold. So - for anyone who has used high-temp paint in a mold and had good result - what brand/color did you buy... figured I ask before I go through the trial and error to find one that works... And not looking for alternatives like Epoxy/Elmers etc.... looking for a aerosol spray paint so I can coat all the small area I have with light coats and not gum it up brushing some thing in the mold. Thanks! J. Quote Link to comment Share on other sites More sharing options...
bryanmc Posted May 20, 2018 Report Share Posted May 20, 2018 Hight temp engine paint is what everyone uses. It is designed to be sprayed on metal, not resin so there must be some sort of solvent in it that reacted with the resin. Quote Link to comment Share on other sites More sharing options...

It's not the mold resin.... it coated the molds just fine, was smooth and had decent hardness to it - plus this stuff is engineer to be painted... it's used in the prototyping industry for models/forms/etc.... but once the plastisol was shot in the cavity all hell broken loose... and on the faces of the mold that were not in contact with the plastisol - there is no damage issue... just where the hot plastic went in... that's why I'm asking what brand/type.... cause the stuff I used (Duplicolor High Temp Cermaic) doesn't play well with baits!! LOL!! J. Edited May 21, 2018 by SlowFISH Quote Link to comment Share on other sites More sharing options...
R Glover Posted May 21, 2018 Report Share Posted May 21, 2018 Try Flex Coat Polymere, That works on plaster molds. Quote Link to comment Share on other sites More sharing options...

LOL!! J. Sorry, I misunderstood which part stuck. The part about everyone using high temp engine paint (never saw anyone say they used ceramic) still applies. Do a search on painting molds and you should get the specific brands. Quote Link to comment Share on other sites More sharing options...
Yo Al Posted May 22, 2018 Report Share Posted May 22, 2018 I wish I could offer more help, but my do-it essential series molds are painted with Duplicolor engine enamel with ceramic. It works great on them. I used Ford gray and use M-F plastic. Quote Link to comment Share on other sites More sharing options...
McLuvin175 Posted May 22, 2018 Report Share Posted May 22, 2018 How long did you let the paint cure before you shot your first bait? Quote Link to comment Share on other sites More sharing options...

I sprayed multiple coats..... the last coat went on 24 hours before I used the mold.... it's possible it didn't cure fully as it's been a little cooler and damp here... but it melted off everything - all layers back down to the mold itself. I did some searches and seems like Rustoleum Engine paint is one of the options that works.... I'll pick up a can this weekend and see how it goes. J.

bryanmc Posted May 22, 2018 Report Share Posted May 22, 2018 Just curious, did you give it 24 hours between coats or just after the last one? Quote Link to comment Share on other sites More sharing options...
SlowFISH Posted May 22, 2018 Author Report Share Posted May 22, 2018 From what I remember 24 before each one... Id spray each morning before I left for work... possible I sprayed one layer at night after work... which would have been about 12-15 hours later. J.
