I got some kind of awful film on almost new
Lexan while
on the hard in
Curacao (downwind of the refinery). After several experiments and almost giving up hope of a cure, this is what finally worked for me:
Have a small
sanding pad
Start with 1000 wet/dry sandpaper and use plenty of
water
Go to 1500 wet/dry sandpaper and use plenty of
water
Go to 2000 ditto
Now you should be ready for Meguairs' PlastX -- it can be applied with a drill and a polishing ball. Every condition is a little different and might take some adjusting but this worked for me.
All of these products can be found in the
USA at a good auto
parts store like NAPA, though the sandpaper may have to be ordered for next day
delivery.
