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.

Maybe it has other brand names, but I use Carlack (or PolyLack because
it has a sailplane on the label). Easy to use and silicone free as far

I use Mer 'Ultimate Car Polish', a UK product, on my airframe. Its MSDS
shows it to be non hazardous and doesn't list silicone, *but* their FAQ
says that their polish contains silicone and that all polishes contain it.

I also use Sparkle on my canopy. Its a US product and was apparently
developed during WW2 to clean B-29 canopies. I haven't found an MSDS but
they say the product contains only water, a mixture of glycols and a
purple tint.

Sparkle is easy:

http://en.wikipedia.org/wiki/2-Butoxyethanol (Oh what's a little
infertility to guarantee a clean canopy?)

Mer's lack of clear marketing is more a headscratcher. There are sites
claiming Mer products are silicone free. As for the Mer website
"silicon" content (note they say silicon not silicone). Who knows what
they mean to say but likely most *polishes* do contain silicon dioxide
or similar. Now whether they contain one of the silicone oils is a
different question. I let the original poster's obvious mistake on
"silicon" vs. "silicone" go by without comment but now we have a
manufacter's web site with some ambiguity.

Been in a number of glider repair shops. Usually see empty New Finish
bottles lying around...

I have used Sparkle before but cannot now find a local UK outlet. Do you
know of UK suppliers?

It was your partner's fault, ehhh ?

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

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...

Never my own glider (yet) thankfully. A wonder considering how often I
land out!

I can't find any UK suppliers either. However, I did discover that AFE
and Severn Valley Sailplanes stock Meguiars canopy polish, which got an
honorable mention earlier in this thread. They also have Plexus canopy
polish. Anybody know anything about this stuff?.

Severn also stock Mer, just in case you can't get it from the local
Halfords.
