Haven't seen a lot of Iron Man suits here lately...
Seams, seams, seams!! Moe's Mk II kit. Out of box, minimal sprue trimming, no putty, no sanding, just snapped together as a father-son birthday present project. Was allowed by junior to paint and decal it though.
As covered in, http://www.hobbytalk.com/bbs1/showthread.php?t=274192 , sometimes "good enough" and "it's better to finish a kit than to be perfect" really applies.
But being who we are, I'm going to sneak a wash in there this weekend and spray some Tamiya clear blue highlights on it before sealing it up for good
