Removing Silicone
I used to use Acetone until someone told me about laquer thinner. I find that laquer thinner works better - and is less harsh. I try to use laquer thinner instead of acetone, in general, if I can. Michael

Silicone removal
We used Acetone and elbo grease. I'm going to have to try Laquer Thinner the next time. Thanks for the suggestion.

How about trying this stuff and reporting back?
I haven't used it yet. http://www.amtexchemical.com/pages/1/page1.html?refresh=1067351487284

Goofing around
Goof off seems to work for me, I have not near the problems that folks complain about on this product. I have taken out 5200 from some tough places too, but glad it was there for the purpose intended. Happy sail and Holidays too...;-)

Boat Life "Release"
"Release: Adhesive & Sealant Remover" made my Boat Life we use this stuff exclusively on boats (both new Beneteau's and boat;s in for repair) it is not as caustic as acetone but does a great job at removing dried silicone residue (after you have used your razor blade to remove most of the big stuff)

Anti-Bond 2015
No, this has nothing to do with Casino Royale or 007.
According to the label Anti-Bond 2015 is "Industrial Strength Polyurethane De-bonder and Multi-purpose Cleaner" for Marine, Auromobile, Aviation, RV, Flooring and Manufacturing uses. It comes in an 11.5 oz aerosol can and is made by JWB Environmental, Winter Springs, FL 32708 877-800-7971. On the occasions when I have used it, it performs as advertised. (I have no connection with this company.) Shipstore.com lists it as: "Discontinued and no longer available. Boat Life Adhesive Remover is a substitute." Maybe the severity of the cautions on the label has something to do with it being discontinued.

Once silicone has cured, I would NOT want to use anything that would dissolve or un-bond it on my boat, out of concern that the product would do a number on gelcoat or f'glass laminate. Silicone is a strange product: I've used it to bond ceramic stuff to highly glazed ceramic tiles and it has formed a very tough & seemingly permanent bond. On the other hand, I've used it in exterior applications (glass to aluminum & metal to brick or wood) and the bond has failed and allowed water leakage within a year. It still looks OK, but peels off in long rubbery strips. It's used with apparent success in a variety of applications, but IMHO, it has no place on a boat, at least not on the exterior. I think there is a general consensus of opinion that supports this.

Well TT, knowledge is key when working with
silicone. Most failures can be traced to improper application. Nothing sticks to cured silicone including silicone. Getting rid of the old stuff is the problem and the leading cause of failure of the new stuff. And silicone IS NOT polyurethane.

I have used the 3M caulking remover .
Scrape most of the caulking off. Then apply the 3M product, let it stand, then scrub it with a 3m greeny pad. Wipe off the area. If silicone is still present, reapply 3M caulking remover. Allow and let set for a period of time then scrub the area with a 3m greeny pad. The greeny pad I am talking about is a basic green scrubbing pad for pots and pans. The local grocery has them as does Home Depot. The greeny pads are a buffing pad. It will not have adverse affects on the gel coat.( in most cases) If you are a polishing nut, buffing out with polishing compound will remove any adverse affects from the greeny scrubbing pad. Most people will not notice anything different after using the greeny pad. Any way, this will give you a surface to bond to with the reapplication of silicone... if that is your choice. r.w.landau

Thanks
I tried the Acetone due to the fact I had it laying around. While it didn't really dissolve the stuff quickly, it softened the stuff enough so I could do a better job of scrapping it off with a blade and finger nail, a scrubby would of probably helped alot. Man, this stuff was really on and from the looks of it it looks like it was put on with a spoon or a trowel. I think there needs to be a caulking license. Thanks guys
