Silicone Sealant Blues

Hi, I'm hoping someone knows what chemical will remove
that %#%$R&@ sealant. One of the former owners of my
(very) used TT tried to stop leaks by putting on that stuff.

Trying to remove it is driving me bonkers. Where it was on
the wood, no problem. Tore out the rotten wall and rebuilt
it. But, its on the metal skin and has to come off to apply
Eternatape. Completely off. Been using a razor blade, but
that leaves a thin "skin" of stuff.....and scratches the
bejesus out of the paint job!

Tried all the usual stuff - Acetone, alcohol, mineral spirits,
MEK, and even lacquer thinner. But no joy. I think that it would
take a multi-megaton blast to remove that garbage. And the
neighbors would surely complain..........briefly.

If you know how to get it completely off, I will be VERY
grateful........

cheers,
johnd

i feel your pain.
Had the same problem in the bath in our house; never did find anythign that even came close to removing it. Even the special "silicone removers" wouldn't even budge it. Like you, about the only thing that really worked was scraping (ever so carefully) with a razor blade.

You could try a product made by 3M, It's an adhesive remover. You need to scrap off the access with a blade then put on the remover. I have used it on windows and fiberglass will not burn or discolor. I had a spot with the same thing and it did work. It might take a couple of tries but it will remove it. One of the best products on the market. Comes in pint cans.

Heres something that be just be worth a try and fairly cheap if it does not work. When I removed all of the factory badges (emblems) from my truck it left the heavy duty adhesive glue from the double sided tape behind. It was a nightmare to remove by hand stuff was stubborn as hell. I read on an internet forum to use an "Eraser wheel" purchased from a local autobody supply. I did just that and all it is a wheel made from pencil eraser material that attaches to a drill. Took the glue right off with ease and did not harm the paint underneath it. Cost me like 15 bucks for it. Now while I am not positive it will work on silicone i cant see it being much more stubborn than the adhesive left behind from the emblems. I'd give it a shot, here a quick youtube video of a guy using and eraser wheel.

Thanks for all the suggestions. Basically you folks say that the chemicals
seems to get the same response that I saw on the general (google)
web - i.e. they work for some folks but not for others..... [I trust
the responses here more than elsewhere, however.]

JFM-jr: Thanks for the suggestion of the stripe removal wheel. Picked
up one yesterday & gave a workout today. Although I disagree with
your claim of "fairly cheap" [$40 made a sizable hole in my Social
Security check!!], it *DOES* work pretty well. Once the bulk of
the silicone sealant was removed, it cleaned up the remaining
"skin" quite easily.

No damage to the metal skins and I even tried it - carefully! - on the
edges of the rubber membrane roof. worked like a champ with no
damage to the roof material.

I sure do thank all of you.....saved my sanity.....
...assuming some exists.....

cheers,
johnd

Yeesh 40 bucks! Its been a while since I bought my eraser wheel but it was nowhere near 40 bucks and im in New York things are NOT cheap here. Glad to hear it worked well at any rate maybe this saves somebody else some headaches down the road.

The 3 M General Purpose Adhesive Cleaner part # 08984 will remove silicone. I just bought a quart last evening for just under $20.00.
