I had to totally strip my rims and then re-coat them when I purchased them from the salvage yard.

This (or similar)is the best thing to use, but use care, it is quite caustic and will burn on contact:

***>>> This page shows the product that I used - http://www.78ta.com/wheelsremove.htm - This guy used the spray version of aircraft stripper. I didn't have much luck with that, I used the thicker, pasty type stuff that comes in a can - MUCHO more effective. The clear-coat immediately bubbled up and within about 20-minutes, I just had to spray off the rims with a strong stream of water, then re-apply as necessary.

Spendy by the gallon, but most any auto-parts store worth their salt can order the stuff by the quart.

Aircraft stripper is very effective, but DANGEROUS <img src="/forums/images/graemlins/shocked.gif" alt="" /> - used in a well-ventilated area and wear coveralls and gloves - DO NOT get on your skin. If you do, rinse with copious amounts of water.

NOTE: found the website - enjoy!
