Hi Terry,
Not sure what paint prep work you did before painting, but that could be your problem. The proper way to do it which very few people do is after stripping to bare metal, then chemically treat the metal, then expoxy prime, then top coat with a hardener added. I did mine like this many years ago and have had no issues. An automotive paint supplier showed me that, and lo and behold its right on the can. I use PPG and their chemical treating is a two chemical process. A good automotive paint shop can color match it for you in as little as a quart. If you dont have spray equipment, Preval makes a good setup for small jobs. Its a glass jar with an aerosol spray cartridge attached at the top. Its fairly inexpensive and gives really nice results, although you'd use alot of them for a wheel. A descent detail spray gun and a compressor are not very expensive either.
There are lots of short cuts; self etching primer, no chemical treating, no hardener, and I've tried all of those, but never get as good results as I do doing it the full treatment.
Hope this helps,
Frank
