The essential prep step for maximum BlackWow durability. PreWow permanently removes stubborn wax and polish residue from plastic trim — without harming your paint.

Why You Need It
Most trim products fail early not because of the product itself, but because of what's already on the surface. Wax and polish residue create a barrier that prevents BlackWow from absorbing properly.
PreWow was formulated specifically to solve this problem. It penetrates and lifts stubborn wax and polish residue from plastic's pores — the same pores that BlackWow needs to absorb into for long-lasting results.

Directions
Dispense PreWow onto the trim surface or onto a firm small brush.
Gently scrub in circles for a few seconds to work PW into the pores.
Wipe with a white painter's towel, then wipe with a clean lint-free towel.
Rinse with dish soap and water, then dry thoroughly before applying BlackWow.
Important
Before applying BlackWow over a PreWow-treated surface, ensure it is thoroughly dry — or wash off the PW with dish soap and water first.
Use PreWow before every BlackWow application for maximum durability.
