removing window sealer


Recommended Posts

Leaving some sealant on the pinch seam should not cause a problem, if it's really "lumpy" then you can take a super sharp knife or razor scraper and "cut" it down. If you completely remove all of the old sealant, then you should use primer to re-seal the bare metal before you use any new sealant. There are also "primer-less" urethane sealants on the market.

This is all exactly right. I am an automotive painter, and all we do is trim it as close to the pinch weld as possible with a razor blade, then urethane right over the old stuff. Like wildman said, just make sure it's smooth, and at a fairly even level! good luck, and have fun with the sheet metal work!
