Ok, now I'm getting confused...
Ultimately, I'll probably try the product (have plenty of polish right now) based on the user reviews I've seen from so many on this forum whose opinion I value, and if the product works, who cares about the marketing.
But, for me, to many of the answers seem to be evasive...
The question posed regarding the safety of the x3 vs diminishing abrasives is the most notable to me. The mention of a 1" thick clear coat was meant to illustrate the point that the amount of cc that has to removed to get rid of a scratch or swirl is a constant, determined by the depth of the scratch, regardless of the polish/compound used. The reply ignored this and instead focused on the fact the cc isn't 1" thick. I'm sure that x3 is safer and would remove less clear than a heavy compound such as Power Gloss with all other variables being the same, but I wouldn't pick up PG and a wool pad to get rid of light swirls. So the question is, how is x3 safer than the least aggressive diminishing abrasive cabable of doing the job?
Also, I have a similar issue with the illustration of rubbing an aggressive compound against the paint compared to x3... if you take x3 and a wool pad, you'd get some marring as well right? if not, why the need to follow up with a second or third pass with a lighter cut pad? It's hard to follow any logic that implies, x3 is less abrasive and therefore removes less cc but, at the same time is capable of removing the same defects as a compound.
Finally, the idea that polishing is what causes swirls is little annoying... everyone knows that compounding, or the use of an agressive polish, or the use of a light polish with an agressive pad, can leave marring that has to be corrected with a less agressive polish or pad, but the same seems to be true of x3, right? thus the 2 (or 3) step process. To say polishing causes swirls seems off the mark as it implies that if you didn't polish your vehicle would stay swirl free.
