We've recently acquired and started working on a '68 overlander. Just wanted to share our experience re clearcoat removal - the Circa 1850 Heavy Body Paint Remover from walmart (canada) seems to lift clearcoat in about 5 seconds - apply liberally and scrape it off before it dries (10-15 seconds) with a plastic scraper (putty knife) and you can get it all off in one go.
We did the whole trainer (26') in 4 hours which seems potentially less time than we'd been led to believe.
Completed test sections polishing with a dewalt 7-9" polisher and we're getting a mirror finish.
For Canadians - princess auto has alot of the buffing supplies we needed - cheap!.
it was also a very clean process stripping as the 1850 is a goo and doesnt run.
Cleaned up with a non abrasive kitchen sponge which can take out any remnant clearcoat (within ~5 mins otherwise the clearcoat hardens again)
