What should a person do for deep cleaning and protercting a vinyl roof on a very nice older car? This was the first I had to do, heres what I did: bug off from malco above the windsheild, washed with malco cw37 (tried myPB super suds but couldnt get the suds to stay up), rinsed well, dried with PB WW (I REALLY LIKE USING THAT!), used malco ez shineSome thing like AA but not as greasy), didnt really like that ,soused some PB NATTYS and buffed. Just wondering if I really screwed up and what others do? RANDAL
