I was at my local Michael's and I saw these next to the sculpey (I was looking for milliput but didn't find any...) I saw Boggs6ft7's mold-making thread a while back and after getting my Trailbreaker custom done, the non-translucent gray cassette "window" is starting to tick me off, so I decided to try my hand at recasting the KO window into a KO...KO window but this time, in translucent red. Has anyone used those? I already know about "alumiliite" but my funds can't afford that much of a hole at the moment and since it will just be a test run to see if it comes out any good, I thought I would try it. But firstly: -I do not have access to mold release and I need to know what I can use instead (would vaseline work?) -has any one used those things before? if so are they any good? and last of all, those two, including the hardening catalyst come up to 33ish (and if the thought of food coloring doesn't go too well then it will be 43). is there anything else I should know about this before I start?
