i don't use it much when i detail my cars. probably once for my engine and several times in the fender wells. i cut it 4:1 into a 24oz bottle and still have alot left and there is no way i can go through the gallon of it. if i used this frequently, then i would probably keep it, but i just don't.
Hey sorry for taking up your time but I won't be buying it... this isn't meant to lowball the price or anything, since it's good compared to online, but at a local Meg's dealer it's just a bit more for a full gallon, plus it's local.
