To OP:
Just to give you an idea of what SI 1500 and Sonax PF can do....here is what I've been working on.
Before (Hood)
50/50 with only Sonax PF (Test Spot)
There were some defects ( the camera had a hard time picking it up) that PF couldn't take out so I did the hood using SI 1500 followed by Sonax PF. This is the result. The surface is bare (no wax or sealant).
