June 7, 201312 yr Anyone have any good tips on getting rid of this stuff? I have my windshied out right now and I'm trying to remove that black RTV silicone they use as a sealant.
June 7, 201312 yr Razor Blade is about the best I've found. There is a "silicone caulk disolver" now at your local home center - never tried it though.
June 7, 201312 yr It's probably not rtv, there is a special windshield adhesive that they use that is black, it sticks way better than rtv. acetone works well to help get it cleaned up nicely.
June 8, 201312 yr It's probably urethane. Talk to a glass person, but I think you are supposed to leave some intact for the new adhesive to adhere to.
June 9, 201312 yr Author I think you're right on it not being rtv. I have a tube of weatherstripping adhesive somewhere that this resembles quite a bit, now that I think about it. The problem is there isn't much left where it needs to be because of rust but large chunks around the edge, and I want to get rid of it before I fix the rust and paint over it.
June 9, 201312 yr If nothing works, or you are short on acetone, try brake fluid. It removes urthane fairly well when it is still wet. I do not know how it works on the hardened one. Sam
June 9, 201312 yr Since he's repainting anyway brake fluid might be worth a try. Just don't use it if your not planning on repainting since brake fluid will destroy your paint job.
June 9, 201312 yr Since he's repainting anyway brake fluid might be worth a try. Just don't use it if your not planning on repainting since brake fluid will destroy your paint job. The brake fluid will soften paint first. It takes at least 20-30 minutes to soften latex, sometimes even more then this. The car paint is much stronger. So there is no big danger here.
June 9, 201312 yr Author I will try both tomorrow and report my findings. I will even wear a lab coat while I do it, to make it official.
June 11, 201312 yr Author the answer is... Putty knife and a wire wheel. Brake fluid did soften it up but didn't make a noticeable difference. It did clean the paint very well. It would work better if you were willing to leave it on overnight, but with the rain coming in tomorrow, I don't have that kind of time. Just a reminder, don't forget to wear goggles when using a wire wheel. I took a needle to the face today.
June 19, 201312 yr Author I was wearing my goggles, but every time something like this happens it just reminds me why I wear them.
June 23, 201312 yr Definitely don't remove all of it on a windshield seal. A little left behind is absolutely fine.
