Iron Man (Mark 1 Gold Armor)
The Mark 1 Iron Man was the first armor that Iron Man built, available only in dull metallic grey. So what if we change the drab grey to fab gold? Bam! Instant armor makeover - you've got an old suit of armor looking new for just the price of paint.
The idea of repainting the Mark 1 armor to gold originally came from lastmaximal and his great Mark 1 gold custom.
