What chromed piece is the problem?
I have touched up worn chromed plastic with chrome nail polish. Isn't right, but it is the most brilliant chrome colored paint I have seen and in small spots you can get away with it. Trouble is if you then polish it, it turns dull.
To be honest, paint never looks right. I saw the best chrome paint job I ever saw on a steel bumper, at a car show last month. From 20 feet away it looked like chrome that needed polishing. But closer...it was obviously paint.
I spent 20 years in classic car restoration as a hobby, and nothing ever really worked except chrome plating or replacement with a good piece.
Driving and working on a Sly 2008 Solstice GXP 5spd 260/260, and the worst-built 2012 LS3 Camaro 1SS to escape from Oshawa.
Gone but not forgotten:
2007 Solstice GXP 5 speed 290/340
Stored and needing to part ways with a 1970 Skylark Custom convertible I have owned since 1989 and turned into a GS455 clone. 462 with 7/8 primary headers, adjustable roller rockers, TA Performance Stage 1 aluminum heads, auto, Chevy 12 bolt, 3.31:1. Sadly a project car now but a driver from '89 to '06.
