i've been workin on my ironman mark 3 suit for over 6 months now and am probably moving into paint next week. so when i say this is a difficult project i'm not trying to be discouraging just trying to help you out. some tips i did learn is that you should try and find the highest def pep files. it may be a pain to pep but it will save you in the bondo phase. oh, and i have a friend who taught me some tips that i really never heard of before on here. what he should me is that after you do your peping, resining, bondoing you can use a putty that is easy to sand and then you can move into priming. its crazy cause before i would just keep bondoing untill it looked perfect but that putty is way faster. also, i think i found some guy who has a mess of spare parts that he's willing to sell. his stuff is super light. i think he used sheets of plastic or something. anyways, i've gotten some parts from him and there pretty clean, so if your interested in emailing him pm me and i'll give you his email.
