I also wanted to clarify something that could be taken the wrong way...
I said "Meguiars is aware of the problem" which could be taken several ways.
But what I meant is that Meguiars is VERY careful in the way they test their products and really go above and beyond. When they recommend their products be used in a certain fashion (i.e. with a rotary on a wool pad) it is because this is the method that worked best in controlled testing.
By using the product outside the recommended method by Meguiars, we are introducing variables that may hamper the performance of the product or cause unwanted reactions.
ie Meguiars recommends using M95 with a wool pad. I used it with a foam cutting pad (by Lake Country) which may have infused more heat on the painted surface which could have directly lead to the filling/masking issue that I encountered. I don't know if that is true, but given the experts at Meguiars have tuned the system and are very open about the proper procedure, the fault doesn't lay with the company but with the person using it (does that make sense?)
On autopia we constantly are altering methods, pads, speeds, mixing stuff together, etc.. we cannot blame products for working outside the very specific conditions they are recommended for.
Perhaps (this is just my thoughts) M95 could be 'tuned' to work better with foam pads, but then they might have to dial out some of the cut (for example, again this is just MY thoughts). Since it was designed to be a heavy cutter, this wouldn't make sense, so Meguiars is very outspoken in the proper way to achieve proper results. I personally wish more companies where as direct as Meguiars, but as long as people like us (always experimenting) are out there, we are bound to find issues with the product as we use it outside its proper range.
