Thanks for the tip on tapered sanding rollers. This is a very useful thread & you guys have done some very nice work. Maybe someone should make this thread a sticky.
I don't!
I've tried just about every clear coat know to mankind and I've not found one yet that doesn't slightly yellow a freshly polished piece.
FWIW:
For a few years I great some great reviews on Zoops Seal, but that changed to negative comments for a few years so I have no personal knowledge if Zoops will slightly yellow or not.
My car probably only see 3,500 to 4,500 miles a year so it's not a DD.
But the first 3 yrs I didn't do a thing to any of the polished aluminum parts and now about once a year if that I spend 2 maybe 3 hrs using a aluminum polishing paste and touch everything up.
I use Simichrome polish and it seems to work the best and last the longest FWIW.
