Tried an "old school" product, No. 7 Auto Polish and Cleaner. Don't know how true the post-Dupont formula is to the original but it is a bit on the runny side. It goes on easy and QUICKLY, gets Oak tannin stains off easily and bug remnants as well(I get most of the bugs off during the wash of course). Leaves a great shine and will bead water for a couple of weeks and then is done. True, it doesn't say wax or sealant so I can't knock it for not beading water longer. As a polish and cleaner, it lives up to the label. Has a neat smell that reminds me of my youth!
