I did a search, but nothing that really answers my question. I thought I knew the differences as SMR has fillers and PIlllMG doesn't. But after talking to 3M's tech line he said they both don't have fillers, but he didn't sound too confident too and even told me that ordering from 3M's website is a rip-off and to buy it from NAPA instead
:shocked
So what's the real story? Thanks!
