Thanks for the tips Kindo!....These projects are the first time working with fiberglass so it's definitely new to me....I left the book set outside for the last week so between the scorching hot sun baking on it all day and the terrible thunder and lightning storms we've had almost every night with torrential rains drenching it, the fiberglass finally cured enough I painted it this evening....I had a terrible time trying to get something that looked OK and repainted 3 times trying different techniques....You can see it isn't near as thick as the original....I'm sure that's because I laid the mold on a flat surface with no mother mold...Doesn't really bother me though....There were other imperfections I believe were caused by having the protoputty too thick....I doubt I'll use the corn starch method anymore because of this and will stick with the dawn detergent method....I'm still really happy with the detail it did capture though....It's nice having a way to make a copy of a rare, extremely hard to find prop I can throw in the yard without worrying about it getting stolen....ZRooo that does look good. i was going to suggest just what you did to see if that would help. hows the weather where you are right now? resin is sensitive to certain weather. I haven't dealt with it in a while but i know it can have trouble curing in really hot or really cold weather. also it might be reacting to the silicone. there might be something in it that's preventing the resin from curing. does it continue to cure once its pulled from the mold? Also if you put to much hardener in this can have adverse affects on the cure as well. resin is a fickle thing. lol! i highly recommend stirring the resin in a separate container first before mixing, this should help as well. And if you heat up your bottle of resin in a warm water bath for a bit before mixing that will help with the cure and it will flow better to help with bubbles. As for the bubbles, do you have something that vibrates? if you put the mold on a vibrator of some sorts it will help bring up all the bubbles. don't know if i missed this but what type of resin are you using? Some work best in layers. if you were to brush in the detail layers and let in cure for a bit until its still a bit tacky then add your fiberglass in layers that might help with curing.
