i had the owner come back today because the SVRT on the mirrors left that awesome streak of product down the door so i took care of that even though i wiped them down after i applied the product...well while i was fixing that issue we were discussing his paint before and after i worked on it and his washing technique which was one bucket, no grit gaurd, cheap towels, cheap wash mitt, dealer washes, and automatic car washes...after showing him all my products and processes i use to prevent swirling up a car he has decided to bring his car back to me every 2 weeks or so to have me wash his car and give it a little pick me up
