Hey, that really caught my attention! I used lots of PCL back in the day, but that was the older *and supposedly *MORE* aggressive version*, and it never did that (although P21s GEPC did on some really soft paint..so the PCL was milder than that by far).
Since I *assume* (uh-oh..) that you`ve tested that MF applicator I wonder what`s with the PCL to do that?!? I`d call the vendor, but then I guess I`m more surprised (and interested in what happened) than a lot of people would be. That stuff used to be about as close to functionally non-abrasive as, say....KAIO.
