Default Best way to remove urethane windshield sealant?

This is actually for my truck. This crap's got moxie! There must be a better way than scraping.

I used rubbing alcohol and lots of elbow grease, but I'm sure there has to be a better way than that, but any way you cut it, that stuff is a PITA to work with.

Default Re: Best way to remove urethane windshield sealant?

Are you removing the windshield or or just the leftovers after removing it?
If the windshield, I use a combination of disposable razor knives (NOT utility knives) and windshield wire which is basically "G" guitar string.
After the windshield is out and you are ready to put in another one, DO NOT remove all the urethane. Instead take a fresh razor knife and just level it down so it's as smooth and level as practical. New sealer adheres best to a little leftover sealant. This isn't just me saying this, it's a know fact. Seems like I saw mention of it on a tube of 3M sealant too. Urethane doesn't bond well to car paint. Car makers put a black "primer" where the sealant goes to help with adhesion. Extreme efforts to remove all traces of old sealant will also remove that primer. Bad.
If you've done all that and are after the goop that got around while installing the glass then you better make fast with some "3M adhesive remover" and a bunch of paper towels. Wipe, wipe, grab another towel. Repeat as needed. Cheaping out on the towels makes smears. Speed is of the essence, that stuff SUCKS to clean up after it's set. Lacking the 3M good stuff, acetone, paint thinner or whatever you have that you hope won't hurt your paint is worth a try. Gasoline maybe?

I had to do some body work as there was some cancer and am now trying to smooth and blend the areas. The urethane is really hosing this effort up as I need clearance on both sides of the worked area. I know I need that primer for the newly painted areas and any area made bare. I just need to get the urethane off in specific areas so I can repaint without painting any of the remaining urethane. I'll try the 3m Adhesive remover as I have another job that needs that anyway. Thanks man.

Well I made several guesses at what it was you were trying to do.. and they were all wrong. The 3M stuff is good for a suprising number of things but won't touch old cured adhesive. I don't know of anything that will.
My solution would be to slice away as much as possible with a razor knife then hit the area with some Roloc Scotchbrite pads. I have a 1/4 grinder I use solely with Rolocs but in a pinch you can mount the Roloc holder in a regular drill.
