This is the 1st time I used the Meguire's M21 sealant wax. Initially, I was using the Tech wax 2.0 but it left grease smudges on my black paint. The M21 really works at reducing swirl marks on my black SRT without removing clear via porter cable/rotary. I really don't want to get into the machines and spend hours on clearcoat removal only to have them reapear again within a short period of time regardless of my diligent wash regimen.
The M21 seems tobe a good filler wax and I think it's due to the fact that it's a darker PURPLE colored wax, therefore it fills in the clearcoat fine scratches to match the base coat color.
