Silicon free polishes?

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.
