first of all it sounds like your mixing two different types of paint if it is doing that kind of stuff.

I painted my rims for racing and also my car.

First step is to clean real good. I even went to the theory or using ajax. It gets rid of everything.

After I let them dry I used a sandable primer. Now take in mind I went to autocolor (a car paint store), not home depot.

Then after a few coats of primer and everything is set up, dry and smooth then I went on to the final stage.

The final stage was I applied light coats of paint. I've been using bumper paint. Now at autocolor they make different colors so I went with a grey color.

I basically misted the rim. By the time I was done I had around 15-20 fine mist coats on either side.

After this I decided to clear them just to protect them a little.

Now take in mind I've been painting cars for a living so prep work I really go to the small detail in making sure it is correct and also in all of the prep work and paint work I did not mix paint types at all.

I used regular emamel paint not lacquer paint. Make sure when you decide to do this again to prep really well.

By the way you can always go to the local auto store (pep boys etc), get yourself of air craft paint stripper and strip the wheel. Once it has done all the spider webbing shit you can not paint on top of it to get rid of it.
