Default Wing re-finishing article

My G102's wings are in need of some TLC and I'm wondering if someone
has some suggestions other than the method described in the article
posted by Al. *My wings are generally in good shape (few cracks or
stains), but the entire top surface feels like 400 grit sandpaper.
Same for the horizontal stabalizer. *The undersides of the wings are
smooth and in good shape. *Even though the wings are rough feeling,
they have a nice shine.

I've tried the WX products sold by Tim at Wings and Wheels, and I've
tried the metal polish and polymer products which were recommended by
Del at DriWash. *No real improvement. *It appears that the wings have
a thin oxidized coating evenly distributed over their surface. *This
happened prior to my ownership as the ship has always been in a hanger
since I've had it.

I'm hesitant to using sandpaper as the gel coat is about 25 years old
and is thin in areas and I don't want to sand any of it away unless
absolutely necessary. *In my case, it seems that the wings need this
oxidation cleaned away as opposed to sanded off, but I could be wrong
as know nothing about gel coat repair.

Any suggestions greatly appreciated.

John.


John you can always try a small patch as a test....

The wings I was working on were finished in IMRON which is a PU paint
and softer than Gel.
I would not however go down below 600 when trying to remove
oxidization.
