I prefer to utilize a spray-on wax while towel drying after a hand wash. For years its been Meguiars D156 which has been great. Looks fantastic and lasts surprisingly long for a spray wax. Well its time to replace an empty gallon again and I was wondering if its worth changing. Looks like the Griots spray on wax is also available in a gallon, though its a bit pricier. Is it a better product? I've been very happy with the gloss of Megs but maybe the Griots will last longer? I do use their One Step Sealant, it has kept my 100k mile F150 looking quite sharp after a fresh wax (though it doesn't hold up exceptionally well its good enough).
