I have an white pad that is starting to shed - its 'throwing' individual 1/4 inch fibers when i tried using 106FF w/ it. I only tried it for one panel (which came out fine) but when it didn't stop 'shedding' i went to a new pad. is this a sign the pad should be thrown away ?
I've shraded a few pads my self, I'm a bit hard on my pads actually...any who I've had a few pads which have been riped/torn and I used them and they still perform but the thing with a torn pad is that it will continue to rip and it just keeps on riping till it falls apart. Well just my opinion though hope it helps.
Use of pad, and also the products used will have a bearing on pad life. Basically, ensure the pad surface remains undamaged: nicks, tears etc are a bad sign. Dont brush them too hard when cleaning them mid detail, as this can cause damage to the foam surface. Another tell tale sign - push the foam down. If it springs back happily, the pad is fine. If it sinks down and stays down, the foam inside is damaged and its replacement time.
