OK, I detailed a 02 Buick and a 05 Chevy Impala back during Memorial day weekend. The Buick was prepped and had PBA/105, the Chevy was prepped and had WG glaze/sealant. These are owned by friends of mine, husband and wife that do about the same amount of driving. The Buick just got back from a week long trip to the beach so it had the good old sea scum on it. I washed both this weekend, the Buick (DG) was still slick and shiney, water beading even on the sides. The Chevy cleaned up well, but the beading was not as tight and completely gone on the bottom 2/3 of the sides. So DG wins in my unscientific real world test. Personally, I use Optiseal - applies easier, looks better, doesn't leave white residue on rubber like WG and lasts longer than either one - again, based on my personal observations on my own vehicle.
