If the air bubbles aren't too bad a good filler primer will take care of them."Plasticote" filler primer will fill up to 1/16" so it's a good name to start with.
Since ESB colors have been identified I would consider using the Panzer Olive Green found at www.testors.com While it hasn't been 100% confirmed that it was used on the gauntlets,it's about 99% and will look better than ANY spray can color used.Think about it 
Unfortunately there aren't ANY decent reference pics for closeups of the ESB suit.What you've probably already seen are what exist.A handful of production stills and promo shots are all that we ESBers have to go on.
Hope that helps a bit.
LMK if you need any of those pics or if you haven't seen them..........it happens 
Good luck
