What preparation is recommended prior to applying seam sealant on vertical surfaces?
Maybe(?):
1. Cut old caulking away with box knife.
2. Scrape remainder with plastic scraper.
3. Clean with acetone.
Sounds like a-lot of work, but I don't trust dealerships to do it "right". Advice from those who have done it? Thanks.
Plan to use:
Proflex RV sealantWhite or Clear?
