I get really frustrated with today's compounds! It seems they have additives, oils, or something, that let them get a nice shine very quickly, but then pretty much wash away, or disappears when I do a liquid polish over them. I recently found the remains of the old Ditzler white compound I used to use, which was one of the best, and I tried it on some parts, and it does NOT do that. It takes a while longer to get the shine up, but it stays there. Are there any types of this old fashioned compounds left on the Market toady? I've tried Meguire's Diamond cut, 3M's Perfect it, and Wizard's, and probably one or 2 more, and just about all have had this problem. I usually use just foams to do my routine, very firm, to very soft, in a compound/liquid polish/glaze/hand glaze or wax sequence. I DO wait a long time before I cut and buff, though, as I prefer not to get dieback, or have to resand and compound after a few months, on my show jobs. So the paint is very hard.
