I detailed my Dad's 94 Delta 88 for X-Mas. Its been waxed once (when I waxed it in 1994), he washes it with some kind of wash mit on a poll, he smokes, and he's got a lot of bird feeders in the yard - if you get my drift. The only saving grace is he usually keeps it in the garage and it's silver. The paint initially looked rather dull. I washed with Dawn, clayed with Clay Magic, applied Meg. Body Scrub with my B&D buffer and yellow pad, and finally one coat of Meuiar's # 20 Poly/Sealant. The results were outstanding. The paint looked very clean and seemed to have a sheet of glass over it. The # 20 applied easily and removed even easier. It leaves a fine white residue (about 1/2 to 3/4 the residue of Gold Class. I removed it with Terry Cloth Towels and finshed with MF. If the durability gives you at least 6 months and the shine lasts somewhat well this would be a great one-step product. (I'm curious how it compares to AIO) I won't get into what several years of smoking does to an interior but I got that looking pretty good also. 5 hours worth - Merry X-Mas Dad ! I've got to get that Dig. Camera.
