I recently tried some experimentation with Comma polish, which is a mild chemical cleaner. The Resin seemed to have an even deeper gloss when applied on top of the Comma - no idea why though
Must be the Comma having better cleaning/prep abilities than the SRP. I too like the SRP, and I apply it by PC/Cylco most of the time. I even "layer" it with another application after 24 hours, as per Autoglym's instructions- put the second application on *very* gently. It does seem to work, the area I did with 2 "coats" held up better than the area that only got one. But you gotta be careful you don't just replace the first one with the second; that's where the "gentle" application comes in.
