i got devcon epoxy. it says super strength 1250 psi for concrete, glass, metal. plastic, and rubber. 60 seconds working time 5 min handling time. for my forearm peices i lightly sanded each side but they came apart so i fixed the problem areas and it seems to be a little better now but it still comes up in some spots a little. but my biceps are like totally coming apart. i didnt sand them hoping to avoid any bad parts like on the arm but it didnt work. i sanded put glue on one side(which i heard you were supposed to do, used these black clams with orange tips on every part. it says 16 piece spring clamp set and it comes in a clear bag. i know ive said allot but any help would be greatly appreciated.
