Want me to scare you even more? My first PT Ltd was black and for some reason I thought a sponge and the hose were enough, no dish soap, nothing else. Then someone told me probably not a good idea, I've been using Meguiars Gold ever since. Tried Zaino, Mothers, Turtle Wax and Pinnacle products and none come close to the Meguiars product. A shameless plug for you Mike!
