I think I should restore one of the headlamps on the 9-3 as it's starting to go cloudy, one issue I've had before is that once you do it then it seems to deteriorate again quite quickly after, what I was wondering is if I get some UV protective film to put on the headlamps would this work better than using a sealant as A. I can't find any sealant B. I've read if you use sealant you have to do it again shortly after.
Anyone got any words of wisdom to offer?
