A spit shine wax job, like a spit shine on shoes, uses lubrication in the wax application process to get wax to "build up." Not many waxes will do it, but Insulator Wax will.
Here's how it works:
1. Dampen your foam pad with QD (I like my Handi-Grip pad because spit shining is a lot of work and your hand gets tired with a flat pad) then load it up with wax.
2. Apply the initial coat of wax to a single body panel, then mist lightly with QD and begin working in more wax. The QD will cause the applicator to float over the wax, and the build up begins.
3. Continue the process until you have a nice coating of wax worked. Then stop adding wax and continue to rub it in with just a light coating of QD and the remaining wax on the pad. You will get to a point where it is almost completely clear.
4. Buff of the remainder with a Concours Buffing Towel.
Bling, bling... nothing will match the finish of a spit shine!
