Ok this is for my Jeep but it could just as well have been for one of my a-bodies since I did this once on an older a-wagon. So a few years ago I replaced the windshield and used roof caulk because I had no money and it's worked for many cars in the past. Well it was too late in the year and it was too cold and didn't set up. I ended up having to buy a can on the way downstate with my kid and slather more on to keep it from leaking.
So now I'm replacing it properly. The caulk at the bottom of the windshield never dried and it comes off with gas. But the stuff that dried is hard as a rock and I can't seem to get it off without scraping it and removing the paint too. Which I don't want to do on the a-pillars and roof.
So far I've tried gas, diesel fuel, marvel mystery oil, greased lightning, goo gone, orange clean. Even with a plastic scraper it won't budge. Gas seems to help some if I leave it awhile but then it seems like it might be starting to soften and remove the paint too.
Any ideas?
