I've fallen in love with this process as a sealer (very LONG term sealer) for headlights after clearing them up. Headlight Restoration-new UV sealant idea
Its a LONG thread but worth reading. In short, mix 50/50 Helmsman clear high gloss spar urethan and Mineral spirits. You only need a VERY little amount...you wipe it on with one of those Scotts blue shop paper towels ($2 for a roll) and then just let it dry.
I did my own experiment....did 105/205 then plastX....it lasted a couple months and then the foggy look started coming back. So i then polished them out again but afterwards added the sealant idea i spoke of above...so far no difference. The link shows people who have gone over a year without doing anything to them in full sun and stay crystal clear. So far mine have gone 2 months or so and they are still crystal clear...and ive heard if you put a little wax on them whenever you do your car..it helps em last even longer, which makes sense to me.
Hope this helps some
