A little dish soap + water avoids that problem when blending aluminum
panels. We've found in our process that SC pads last longer and yield a
better finish than AO pads.

Using SiC really doesn't help at all because just as soon as the aluminum
starts sticking to it, you end up with the same problem. The only thing to
do is to use a lubricant to keep the aluminum from attaching itself to the
abrasive and thus cause the problem.
