I'm not really a detailer and cleaning cars is not my thing at all, but I've been wanting to attempt to improve the tired paint on the 2006 Lacrosse my grandfather left to me. The paint still had shine to it, but it was very scratched and had some heavy acid rain damage on the top surfaces. Most areas looked like this-
So earlier in the week, I washed and clayed it, pulled it in the garage and wetsanded the roof, hood and top of the decklid with 3000 Trizact. I followed up by DA polishing with Meguiars M105, M205, and then Chemical Guys P4, each on a progressively finer polishing pad. After all of that, I waxed with Collinite 845. The result isn't 100% perfect, but it is significantly better.
I also did the headlights. I've polished them before, but I didn't clearcoat, so they became hazy again very fast. They have some crazing going on so they'll never be perfect, but this time I used a Cerakote Headlight kit with a clearcoat and the clear definitely makes the crazing much less noticeable. Hopefully it'll protect them and keep the haziness away for a while too.
