Guys, I have been one of the ones saying that Blackfire SCR is the same thing as Menzerna SIP 3.01. I got that information directly from CMA, while talking to one of their reps using the Live Help function of their web page many months ago.
Here is a cut and paste directly from the properautocare.com website, Blackfire Scratch Resistant Compound page:
<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
In 2005, we approached Menzerna of Germany and asked them to adapt their state-of-the-art, ceramic clear coat polishes for the enthusiast aftermarket. Menzerna, working with Mercedes Benz, developed a compound and polish to remove defects in the new nano, ceramic particle clear coats. These polishes are currently used at the OEM level in various auto manufacturing plants world wide and are considered within the polishing industry to be the most advanced polishes in the world.
So why change them?
Polishes developed for the assembly line, are designed for finishes that have been oven-baked but before the clear coat has reached it's maximum hardness. These polishes may dry too quickly when used on fully cured, scratch resistant clear coats. To facilitate the extended polishing needed to remove defects in cured, scratch resistant clears, Menzerna added additional lubricating oils to their OEM formulas. This means the enthusiast can polish longer without fear of creating excessive haze.
The result of the Menzerna-Blackfire collaboration is BLACKFIRE Scratch Resistant Clear, Finishing Polish. This formula is exclusive to BLACKFIRE and offers the do-it-yourself, enthusiast a number of advantages

Sounds like they allude to this being SIP in the above text.
