Time to tackle the back window in my 355 Spider. The 360 was much easier...compound then polish with an electrical random orbital (RO)..Done. The 355 had a sticky film on the inside that did not come off with Windex or other cleaners. I started with the RO and a high cut compound 1000 grit. After some time, the RO cut through the film which is what I wanted. I gently scraped the remaining film off with a plastic hotel key, my fingernail and elbow grease. Next I used Scratch&Swirl compound then Polish followed by wax. Hope this helps someone. Image Unavailable, Please Login Image Unavailable, Please Login Image Unavailable, Please Login
