will plasicine stick to fibreglass resin? Answered

im having a hard time getting some normal grey clay to make rock climing hold moulds and was thinking if i could use plasticine instead?


Large lumps of resin can give off a lot of heat as they set. Plasticine melts pretty easily.

that should work fine - it shouldn't stick at least; nothing sticks to it. Your original will be destroyed getting it out of the mold, particularly if there are any undercuts.

I would recommend molding silicone to make the mold instead of resin...unless you're talking about molding the new parts out of the resin.
