The window frames on my 2004 2520XL are in bad shape with a lot of corrosion issues. The corrosion has not pitted the metal yet but it is unsightly and I cannot get it to polish out. I am curious if it is possible or more importantly how difficult would it be to pull the frames out and remove the glass and have the frames powder coated? Or does anyone have any other ideas of how to make the frames look better? Also the carpet in the PH and the cabin has a lot of stains, most of it from rusting stainless steel bolts and nuts. Is there any way to clean it w/o having to remove and replace it?
