No kit. I sand/clear them. In looking closer, I may be able to improve them, however. I tried some adhesion promoter this time and I think it is adding to the cloudiness. I'll sand 'em down and re-clear without the adhesion promoter before I reinstall. They're enough of a pain to remove that I'd rather re-do it while they're out.
Here's a video of the method I basically use. If your lenses are clear on the inside, they turn out crystal clear using this method and tend to hold up much longer than polishing them and leaving them unprotected. The other reason I like this method is that it's pretty easy. You don't have to sand excessively - just get the bad stuff off, work your way up to about 1500-2000 grit paper, then clean and clear.
