I have only used siphon blasters, so can someone tell me how much difference
the pressure makes? Does it slam into the metal harder causing more pits and
damage or is it a volume thing? I was pleased yet annoyed with the siphon
system. It never clogged or stopped.. ran very smooth and did a perfect job.
Yet it was very slow going. On the other hand, I do not want something that
will damage the sheetmetal using the same grade sand.
Thanks!
