haha sweet crap man ! lol when i first clicked on the picture i thought this was a vacuforme kinda deal for the chest peace. nicely done man... i'm assuming you used bondo after resining it and then just sanded everything down to the perfection we sere here right now ? (and by the looks of it, primed it...)
I fiberglass the inside of the model with fiber glass jelly (found at walmart in a green can)and the cloth, first paint on a leyer put cloth down and paint on another layer on top of cloth then continue all the way around till finished.
then use bondo also found at walmart, use that to coat the outside, there is a skill to it so just dont slop it on like most noobs do, section it off and slowly build it up, put on the first layer, I like to use a husky knife to carve it away when the bondo starts to get hard (feels like cutting soap) that way I save on sanding. put on the second layer with a piece of plastic or old creditcard type tool and scrap it in so it starts to smooth out the holes. you may need to do it a 3rd or 4th time to get it very smooth, use med and fine sandpaper.
if you need detail that sticks up draw out were its going to be tape it off slop some bondo over it, and peal the tape while its still very soft, then when it get to the soap use that knife again to carve out your details make sure you do it while it still soft because once it hardens its hard to work with.
!!!and read all saftly instructions make sure you have all the right gear dont just do this in your living room these are chemicals!!! goodluck
Wow, I'm impressed! I keep getting the whole 'use the paint' kind of resin advice. I didn't know you could get it at walmart! You just helped me too, I have my costume on the way, I just have my CQB helmet pepped. My boyfriend will help me with the finishing touches when it comes that time to even paint. He told me an example to make it look like worn metal.
