Windshield Sealant

Post by GeorgeG » Tue Nov 06, 2018 12:22 pm

Anyone have an easy method for removing the old sealant around the outer edge of the windshield? I have the windshield out and need to replace it. Want to clean it up before I do that.

On my 55 I used a heat gun to gently warm it then used a plastic putty knife to scrape it off. Don’t get it too hot or it gets gummy and you can also blister the paint. Finished up with WD-40 and a rag to clean up the residue. Laquer thinner or paint thinner would probably work faster but I didn’t want to damage the paint.

Good idea! Thanks Greg. All the gunk is on the windshield itself so I don't have to worry about the paint. I'm not even sure what all the stuff is. Probably not only sealant residue but weatherstrip droppings.

If you’re reusing the windshield, don’t appy too much heat to one area or you WILL break the glass. Been there done that when I used to install car phones eons ago.

Thanks again for the advice. I'm just trying to save some money, and maintaining authenticity, by reusing the original windshield. If somehow I mess up, or the original piece has too many scratches/chips/etc, I'll bite the bullet and get a new one.

If just cleaning the glass try a razor blade scraper or a single edge razor blade in a vice grips. Wash with lacquer thinner and again with alcohol.

Just a follow-up to all who offered suggestions. The weather finally cooperated so that I could move out one of my project cars to free up a bay in my garage and make room to clean the crud off the edge of the glass. I used my go-to cleaner, Brakleen and a razor blade tipped window scraper. That got most of the heavy goop off. Then I followed up with Windex (lots of Windex!). For a couple of really tough areas I had to use a very soft scrubby with either Brakleen or Windex depending on the strength of the residue. Worked like a champ. Now I have clean glass with the original etched Ford logos.

Next I have to see if I have the guts to try to install the windshield and rear window by myself (and a couple of neighbors), or find a pro who still remembers how to put in these old windshields.

I realize I'm too late here, but maybe this will help someone else... Just pulled my windshield last night. Used 3M #08984 General Purpose Adhesive Cleaner - worked quickly and easily. Highly recommend. Available on Amazon if you don't have a local supplier.

I used the same stuff when removing any kind of old adhesive from door jams,trunk . etc... It's a great product works fast.
