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.

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.

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.

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.

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.

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.

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.

I will try both tomorrow and report my findings. I will even wear a lab coat while I do it, to make it official.

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.

Ouch either way.

Glad you survived.

I was wearing my goggles, but every time something like this happens it just reminds me why I wear them.

Definitely don't remove all of it on a windshield seal.  A little left behind is absolutely fine.
