Hey George,
First off this is a great thread. I have an 07 BMW E90 and my headlights were involved in an accidental drop of a spray paint can while cleaning my garage and the can got punctured and sprayed all over the front of my car and other stuff. The only thing I had on hand was goof-off to clean off the green spay paint and they were left with a hazed/pitted/scratched, they weren't in the best of shape before the incident. The H.L's were the only area of my car that I couldn't get "repaired". So anyway I used Meguiar's H.L. restore kit, turtle wax H.L. restore kit, and then I found a company that has a professional kit (Dvelop), and still fine scratches are still there. Oh yea then I got the mother's red buff ball for the drill, I forget the exact name but used that with the polish that came with the Dvelop kit and scratchX (I think Mag's). What could be my next step. I used wet-sand paper grit 400, 1000, 2000, 2500, and 3000. Dvelop included only 400, 1000, and 2000, when that didn't work I used 2500, and 3000. I've restored H.L's on a few cars/trucks and came out great, but the BMW is really aggravating me. Should I go with M105 and/or M205? and what pads do you suggest? I figured I'll give you the whole story so you know where I'm at, so I apologize for this long question. I guess I would say that I'm not very knowledgeable about buffing and polishing plastic or painted surfaces except for the previous headlights I mentioned earlier. I tried inserting images but they were too big or something, if photos would you help me maybe there is another way for me to get you photos?
Please save me.
