Mr X (T-00) Cosplay suggestions and or other help

Well I already have a posting of this up on cosplay.com but I think I'll make a posting here too just to see what other opinions I can get on my said cosplay. For next years San Diego Comicon I really hope too attend as Mr X from Resident Evil 2. Given the fact I'm 6,4 and about 300 pounds I think I defiantly fit the build of this character. But I'm just having a hard time trying to figure out how I'm going to make the metallic looking parts on the gloves, as well as the iron cuffs on his wrists. Oh and if anyone knows a place where I could find trenchcoats in XXXL sizes I would DEFINTALLY appreciate it.
