Mike,
When I bought my '30 coupe, it came with an aluminum WS frame. No Glass with the car at all. So it presented a problem. I found a good Glass Man who was very reasonable so I went to work on the WS frame after the glass was installed. I polished mine about 2 months ago.
1. The first thing I did was to
COVER THE ENTIRE GLASS WITH DUCT TAPE.
2 Once that was done I carefully ground off the corner welds (still in the rough in the two bottom corners). You gotta be careful doing this. Just take your time.
3. Once this was accomplished, I started with some
medium wet-sand paper to get any knicks that came out of it. I did this by hand in a straight direction with the frame.
4. Then I went to to a finer wet-sand paper (800 - 1000 grit asI recall) and really smoothened the finish.
BY THIS TIME, THE FINISH WAS ALREADY LOOKING GOOD, BUT NOT GOOD ENOUGH.
5. Then I proceeded with an
ALUMINUM POLISHING KIT. It came with polishing wheels and 3 grades of compound. When I finished with the last grade, I cleaned the whole thing off and it looks like CHROME.
6. Last but not least, I removed the tape.
I have not clear-coated mine yet but probably will. I couldn't wait to get it on the car and go for a drive. I'm sure my windshield blinded all on-coming drivers. LOL




Good Luck
