When you take your car/van/SUV/truck to one of those full-service car wash places, one of the basic bare-bones packages available is invariably the “Wash + Foam Wax and/or Sealer Wax.” And, sure enough, when you see your car inching down the wash, it’ll cross a structure after the rinse cycle that has big, friendly neon letters lighting up “FOAM WAX” or “SEALER WAX” as it sprays some thin, watery stuff on your car.
Needless to say, I suspect this stuff is just so much useless liquid. Even a beginning automobile owner knows that the minimum level of waxing that’s worth a damn is old-fashioned hand waxing, where you scrub the wax into the body, let it dry, then buff off the excess. Surely, if foam wax/sealer wax was worth anything, people would use that instead, and wax their cars in one fifth the time (“Just spray it on, then dry off your car, Hoss.”).
So, does anyone know what is in that Foam Wax/Sealer Wax stuff? Is it just water mixed with a miniscule amount of oil? Does it actually do anything worthwhile? Or is it (as I believe) just a fancy way to skim money from gullible customers who will believe whatever a bright neon tube tells them?
