Yep still here.
I ended up using the Por 15 ( 2 part - epoxy like ) clear coat. Expensive ! I bought the quart size....way to much for the 4 wheels. The smaller size would have worked. I did use the prep solution they sell....and the wheels were new.
I was concerned about it setting up before I had all of the wheels coated so I wasn't as careful as I should have been. Where I put it on a little heavy I did get some small " curtains " ....not a big deal for me. They were right on when they say that it does not leave brush marks.....as it cures it just sort of blends the brush strokes together. I was only interested in preventing oxidation.....I'm not into the shiny polished show wheel look. They look good ....hard to tell they were coated unless you get within touching distance. My goal was to never go back and polish / wax, etc. so far it looks the same as the day I put it on.
I coated the bead areas also ....I've have Aluminum wheels corrode between the tire and wheel before and develop leaks.
This stuff has been on since July......so for so good, hardly a longevity test, and I'm more interested in the results 10 years from now.
If I had to do it again.....I'd consider spraying it on, but that would be more $$......so maybe not
Hope this helps.....sorry for the long winded reply.....but feel free to post if there's any thing I didn't cover.
