I have client that just wrapped his car in matte white vinyl and is looking for some tips on washing it. I have never had to deal with this finish so am looking for some insight.
The key would be to incorporate a regiment that would reduce touching of the vehicle to bare minimum. Powerwash pre-rinse > Grit-Guard > free-flushing sponge > Leaf blower > light QD with extremely soft towels (borderless Zaino Towels).
