Re: [bolger] Re: Help needed
Thanx Bob. I will try to scrape it off and maybe some alcohol if
necessary. It should not be necessary to remove everything (silicone
i.e.) though.
Final results will be reported.

Dow Corning OS-2 Silicone and Surface Prep Solvent may do it. My 25
year old Lexan Mfg specifcation says NEVER use Benzene, gasoline,
acetone or carbon tetrachloride on LEXAN sheet products. Compatible
cleaners listed are Formula 409, Freon TF, Joy, Palmaolive Liquid, Top
Job, VM&P grade Naphtha, Windex with Ammonia D. (none of which are
likely to remove silicone. Search "silicone removal" on Google and you
will see many sources of info. I suggest a call to your nearest Dow
Corning distributor or better yet factory rep. Dealers are not much help.

Does silicone sealant bond to cured silicone?
[I think it does.]
If yes, then you may not need to completely remove the old silicone.
Doubt it. Try to desolve small samples. I would bet that anything
that desolved the silicoe would trash the lexan.
Try gentle heat with a hair dryer, maybe?

I had to remove some of the windows of my WDJ, partly due to the repair
of the leeboard-brackets og partly because they leaked. The windows have
been fastened to the hull with ordinary silicone sealer (sealant?) and
galvanized screws (to be substituded with brass screws). Before
remounting them I have to remove the residue of sealant from the
windows. It sticks like nothing I have seen. Somebody told me that using
solvent on lexan windows is contraindicated - they would disintegrate.
Scraping of the sealant from six BIG windows is one h... of a job -
besides the side effect of scratching the surface.
My question: can I use some sort of solvent?
