*Jon: i have a question, i've tried the Megs 105 and 205 as well as SwirlX and Ultimate compound, and at some point they also become clear, does that mean it has reached its cut? or can i still go on and it would still provide me some more cut? Now that you mentioned about SMATs and traditional polishes becoming clear when broken down, i was just wondering if SMAT becoming clear would also mean it has reached its cut limit? I've used 105 and 205 on an old BMW and based on how i look at it i think it also looses cut after sometime, but the good thing i noticed was even if its clear already you could still polish with the residue to produce a great gloss, same things with UC on a PC.
