hi all, made a few moulds for my motorcycle with poly resin, the moulds came out perfect so bit of wet an dry then polished with g3 to a mirror finish , waxed and left overnight then followed by another 10 x waxing. came to release the split moulds and they are stuck fast, theres no machine lock so in the end i smashed them apart and the parts are fused to the moulds which ruined the lot. ive made moulds in the past with no trouble so suspect its the g3 , if thats the case then can someone recommend an alternative to polish my moulds without them sticking ?
