I don't understand what the deal with Menzerna's scratch resistend clear polishes (PO85RD, 106FF, and Blackfire's version). Don't get me wrong, I think these polishes are simply amazing...but they work just as well on regular clears as they do on cerima clear. And this whole Blackfire SRC polish warning on CMA really baffles me...this this the safest, best finishing polish I have ever (EVER) used. Personally I think this whole "SRC" bit is a gimmic. I mean it isn't like the abrasives never break down (or take longer to break down), making them better for really hard clear; rather, the abrasives break down quite nicely and I have found the Blackfire SRC polish to be my best polish for soft clears, espcially on black. I think they are amazing polishes, likely due to the small size and uniformity of Menzerna's abrasives...there just isn't anything I have found that would lead me to believe they's work better on cerima clear than they do on regular clear. They are simply really good polishes...like FPII with a higher concentration of small abrasives.
