Just did this a few months ago, mine are holding up great so far.
Products and process:
- Cleaned with Adams APC and a mf towel
- Taped up and clayed with Adams clay and ONR as clay lube.
- Wet sanded with 800 grit, then 1000 grit, then 2000 grit and a sanding block
- Polished with Optimum Hyper Compound on a 3" LC wool pad and a cordless drill
- Sealed with two coats of Blackfire wet diamond for now as I plan on coating the car after I complete the entire detail over the next several weeks.
