Hey guys
I want to try casting some car bodies. I have cast stuff before using hobby lobby supplies (Alumilite). Every time I cast something it comes out hard, but sticky.
I have tried heating up the mold, tried keeping a heat gun running on the mold while it hardened. I tried more hardner, less hardner and it always comes out sticky on the surface. On past things it hasnt been a big deal- i sand it off and then paint but on a car body which is already thin I think it could be an isssue.
Is it the cheap-o resin from Hobby Lobby or am I doing something wrong?
