Washing with a solution of Dawn, all purpose cleaner, and warm water should remove a majority of sealants and wax. Claying next will remove whats left so any left over surface protection should net factor into this.
I don't have any experience with Surbuf pads however lets ask a few questions and see if we can help move this along.
Closeup photos showing the surface defects would help allot.
Meguiar's M105 and M205 are staples of the detailing world are the baseline which many products are compared.
These are some of the basic questions I would ask that might help get to the root of the problem.
- Did you prime the pad enough so the compound is working between the pad and paint and not being absorbed into the pad?
- Is your polishing speed set between 5 and 6?
- Are you working a 2' X 2' section
- Is the downward pressure sufficient enough to allow the pad to rotate and correct the finish?
- Are you performing 4 to 6 complete passes per section?
- Are you moving the polisher to fast, not allowing it enough time to work?
There are many things that could be coming into play here but not seeing it or being there makes it difficult to diagnose and resolve.
