My bad, got sidetracked.
Allow me to explain.. the above pic is the after. The before was a nice, uniformly painted bumper. Cause: me and this:
Not even a rotary... just me and a PC.
I was attempting to remove some particularly stubborn residue/sap/ I don't know what. It was hard as a rock. Aggressive clay, wd40, aio, fp2... couldn't touch it. Out came the edge orange and the OC. And this is the result. I guess I should be excited, I got the reside off, but... I seem to be in need of some paint work now. This was last week.... its taken me this long to come to terms with what I've done.
To answer quesitons perhaps before they come in... the pad was level on the top of the bumper, about 15-20 lbs of pressure (normal for me, never any problems before). I noticed the residue start to come off, and then took a few more passes, and on the las tone, noticed that there was white/gray under the pad instead of shiny black. Picked up the machine, looked at the pad and smelled burning foam. The foam apparently got depressed (I don't know how with the amount of pressure I had on there) to the adapter which burned it, and then the plate in the middle took off some paint. At least, this is the best I can I figure out.
So... I'm thinking nice little mix of user error, perhaps a defective pad, and some bad luck. The pad was as pliable as a mf applicator when I went about inspecting it after the mishap (after breaking a lot of stuff around the garage)....
I'm not saying don't buy edge.. I'm not saying edge makes bad products. I'm saying be carefull with edge pads around corners.
I'm here to help you learn by making the costly mistakes for you, so you don't have to.
