Chrome paint always turns out like crap (the same with any paint that claims to achieve the look of plating whether it's chrome, gold, whatever). I've seen photo's of a couple "good" jobs and still in real life they look bad. Either get the parts powder coated or truly chromed; removing and cleaning off a bad paint job is miserable. Remember, as with anything on a Supra, cheap often ends up costing you MORE.
That's my advice and I'll shut up about it now.
