i will try to get a picture up tomorrow or wednesday night, and i have changed the surface. i took it down to 3000 with a new pad and left it at that and i got the same result, just not as fast. the cover seems to just not be able to handle oil. if i throw more than a certain number of shots in a given time frame, the surface stays oily and has a film on it, and doesnt come off when cleaning it, but goes away over night. but while bowling, it can only handle x amount if shots until it stops moving
