Since I winter drive my 850 it gets some wear from winter like any other car would. Every spring I usually deep polish and seal the car to give it a fresh look and upkeep the body condition. This spring has been really wet and I haven't got around to it till recently. Take a look at the pictures of me masking all the windows, trim and stuff off and polishing it then sealing.

I used my variable-speed DEWALT DW849 rotary buffer, with two swirl remover pads. Pretty common pads from your local autobody supply. I usually use Meguiars Swirl Remover 2.0 for my initial polish, and then seal it with Meguiars Show Car Glaze. Works like a dream.

I didn't do any 50/50 shots as I was short on time, but these will give you a good idea of before and after results. Here are the pics of the process:

I took the time to mask everything off really well because cleaning out wax out of tight places and windows is a true pain.

I masked off the trim and everything too, just never got the pics of that.

This is what the end result looks like. Pictures taken the next day since I ran out of sunlight and wanted to double check my work in the sun.

Just some dust particles that settled overnight from sitting in the garage.

Ready to drive =)
