PPG Specialty products

Has anybody used them or know anything about them? They`re made by Meguiars for PPG. I got a bottle of SC1 (maybe SP1? forgot) Quick Cut Compound and it works great, I`d call it DACP on steriods. It cuts very quick, then seems to break down into a fine polish, there was no need for a polish step after compounding. I`d really like to know if these are just relabeled Meg`s products or if it`s a total different formula. There really isn`t any info on product usage or abrasiveness on the bottle.
