I got a bottle of this and another polish about 5 years ago. From what I can remember, the Advanced Swirl Remover was an okay product in regards to removing defects. I do not think it finished down LSP ready, however I didn't do things then the way I do things now and immediately followed up with the less aggressive Pinnacle SMR. I seem to think it might have dusted quite a bit too.
I still have a little of this left, on a back shelf. I just haven't really felt the need to use it as I think I've come across some polishes that suit my needs a little better in the last couple of years. HTH.
