C4 clear coat wheel resoration
Thanks for the input. I have a 92 with stock clear coat wheels. The previous owner overdid the auto carwashes and the acid cleaner combined with the abrasive brushes lifted the clearcoat in a circular pattern fanning outward. Several mobile repair units in my area, (one was
www.rimguardextreme.com) agreed full strip, repolish and recoat was necessary @$150 ea. and 8 days at the main shop, not the mobiles, ugh.
At this point they are not that bad, and the rears are the worst. My local body shop said I could improve them with sanding. At least they won't corrode or peel further. This was what I did. I masked the wheel openings and center (where lug nuts are) then sanded the clear coat off in the center with 600 grit. Down to 400 is OK too, just follow the circular machine marks. Use 800 grit WET next, using hose or rewetting sand paper constantly. Now use 1200 grit WET again, to smooth, rinse and allow to dry completely. Wipe entire area to be sprayed with rubbing alcohol to remove all traces of dust.
Apply at least 2 light coats of clear, following spray can instructions. Don't apply too much at once to avoid unsightly drips. I removed some tape and polished the center caps, covered the lug nuts, and resprayed the entire wheel. Remove the tape and enjoy the improved appearance and protection. Just take it slow and this may buy some time. I was even able to sand away mild curb rash. I hope this helps someone in a similar predicament.
