I figured I had to post since you guys linked my thread which makes me feel all warm and fuzzy inside
I actually redid my lights again - mainly because I was bored and looking for something to do to the LS...I had the bumper off anyway (put on an LSE) so I figured I would spruce up the front end.
The lights were obviously in decent shape since it wasn't too long ago that I refinished them but I used the same instructions (for the most part) as I did in my original write up. I've found that the minwax/mineral spirits works well and really brings out shine but like jmtiseo said, it can be tricky to apply. Since I'm a headlight restoring veteran at this point, it didn't take me nearly as long. The polishing stages are really where it gets time consuming but are super important to get out all the little scratches and any haze. Now that the LSE bumper is on, I plan to do a full detail in the upcoming couple weeks. I recently got a heavy duty buffer/polisher and some quality cleaning/waxing products so I'll probably have some pics at some point.
Oh - and for scuffs on interior plastic, I find that simple green and spray nine work pretty well. Be careful though. They are both pretty powerful and can make the color of the plastic appear a little "off" when compared to other pieces.
