Wedge Replacement Sealant Question

[kbmelling]

So, after epic wedge failure number two, we've decided to upgrade to the floating wedge. Wedge arrived yesterday with instructions from the dealer that it shouldn't be a problem at all to make the switch. However, after removing the old mounting bracket, there is substantial quantities of silicon from the previous seal on the fiber glass. Does anyone have any suggestions as to how to remove this sealant/any experience with this? Obviously I don't want to put the new bracket on top of the old sealant. I started using a metal razor, but that gouged right into my gel coat, and still seemed to leave a residue. Any help would be appreciated.

Also, my dealer recommended I use "Boat Life Life Seal" as opposed to 3m 5200/4200 because it is easier to remove and provides just as good of a seal. Any caution to using that?

Acetone or a similar solvent will help remove the old silicone residue, I've always used a plastic scraper to get the bulk of the stuff off.

DO NOT use 5200 for that seal, you will never be able to remove the bracket without damaging the gel coat of the boat.

No experience with the Boat Life Life Seal but just find a silicone sealant that is rated for continuous underwater use. I know 3M makes one - just look hard for the underwater rated stuff.

Plastic putty knife or a very stiff (they come in several stiffnesses)metal putty knife. Try alcohol, acetone and lacquer thinner in that order. MEK is the nastiest non commercial chemical you can get without a license... Find it at paint store... Not sure what anything harder than acetone will do to gel... It's not like it's on the deck though. All your damage should be hidden by the new wedge plate.

I'd use 3M 4200 or 100% GE Silicone. Alcohol works wonders on cleaning up wet silicone!
