I finally got to use my 3M 150 mm Perfect-it III High Gloss Polishing Pads (09378) (Black) and Ultimate 100 mm Polishing Spot Pads (Blue) this past Wednesday. To say the least, I was very happy and content with both sets of pads but unfortunately the backing pads to the Ultimate blue pads began to peel around the edges.
Now I'm not sure whether that started happening before or after I used my UPW to clean the pads today but I thought I'd give everyone a heads up as this may be a potential issue for those of us who own the Ultimate pads. I have yet to try the orange and red Ultimate pads but will keep you guys updated if I experience similar results.
I really like those Ultimate pads but if I find the backing pads to behave like this due to minimal pressure with my
PC and 3.5" flexible backing plate from Excel Detail, I don't see myself purchasing anymore of these.
