This concern for silicone contaminating a glider surface making it very difficult to complete a durable repair does not seem to be a valid concern at this time.
I have had many long talks with commercial repair people.
They just assume that every surface has silicone on it because it is in virtually all products.
They have told me repeatedly over the last ten years that silicone is NOT a concern.

Back when Larry Mansberger had his shop at Minden, I asked him about all the flurry about silicones in waxes etc. At the time, and probably still, most of Consumer Reports top rated waxes had silicones. Larry said it wasn't a big deal, they solvent cleaned and prepped surfaces before repairs is any case and that silicone contamination wasn't a concern.

Good enough for me.
