Out of curiosity, how do auto body shops deal with silicone waxes during
repairs? Must they strip an entire panel down to the primer (or bare
metal) before repainting? Or do they simply replace panels?

Thanks for the info & link Darryl. I believe Pledge has changed
formulations over the years, good to know what is in it now (maybe it was
always in there...?)

But yes, most of the "wipe on/wipe off" stuff has silicone in it. While a
shop should "assume" silicone is on the surface, it's nice to not find it.

As to a wash, I stick to what I use followed by a good paste wax coat at
least a few times a year.
I suspect it always has had silicon oil in it, even though it was
initially marketed with slogans that said "wax".... but then it's neither
a "polish". Misuse of all those terms in marketing is unfortunately
common in finishing trades. Pledge came out in the late 1950s and
Silicone oils started being used in the 1950s. e.g. hybrid wax/silicone
automotive car waxes were patented in the early 1950s. And it started
being added to lots and lots of products.

Surface prep cleaners used properly. Care not to spread contaminants around
e.g. on sandpaper. And use of compatible paints/additives (actually
typically a silicone oil derivative itself... which lets the paint flow out
over silicone contamination).
