Silicon free polishes?

Many years ago I attended at talk on gelcoat maintenance by Mr. Schneider
(the "S" in LS)

He clearly stated that it does not matter at all if polish used on glider
surfaces contain silicone. The reason: exactly what Bob also notes, no
professional repairs can be done unless the surface is ground way beyond the
depth to which silicone can penetrate.
I guess he should know. I have since then used silicone based polishes on my
gliders, and I have also had them repaired (dont ask..) without any
complaints from the shops

Easy to use and silicone free as far
as I know.


I would bet that repair shops clean, clean and grind all old areas back
to degree that there will be no problems with any product used on a
surface.
There are so many contaminants floating around that a repair shop must
go through a careful cleaning of the damaged area before any work is
started.
So, I doubt that it makes any difference as to the brand/type of polish
used.
Your opinion may vary.
Jump in.

I'm by no means an expert (just a guy who does an ocaisional minor
cosmetic repair or refinish now and again), but my mentors taught me
to start every project with copious amounts of 3M Prep Solvent (or
equivalent) to remove wax, oil, grease, etc. This usually meant two
passes using new (clean) paper towels for each pass. Never had any
problems with gelcoat adhesion...
