Cracking clear coat on Corvette wheels

The clear coat on my stock 84 Corvette wheels is cracking and has a dull look. What are my options? If I strip the clear coat what is the best stripper to use?

To strip your wheels, look for a hot sand dip similar to that used to strip paint racks. Use the minimal temperature you can (recommended by the stripper) and keep in mind that aluminum will melt around 1500 °F and deform at less of a temperature. 800 °F is adequate to sinter the powder and will most likely leave your part in pristine condition. After burn off, hit it with a quick baking soda sand blast and start from scratch with the pretreat/coating process.
