I love BF products but as far as polishes, only used the BFEP. I've used Meg's D300 compound and love it. Would BF SRC compound be the equivalent to D300? Would I use BFEP or a different finishing polish after the BF SRC?
D300 has a little more cut when used with a microfiber pad, as this is specifically what it was designed for. IIRC, when I was part of the pre-beta test development team for this product, we were informed that it does have some silicone in it to help the polish flow over the fibers for better cutting.
On a foam pad, both products will have similar levels of cut (again D300 will have slightly more), and both finish extremely well, although I find SRC Compound to finish slightly better.
Both products are very great and high quality. Ultimately, if having a body-shop safe formula (silicone free) is important, then SRC Compound wins, hands down.
