I just tried out a EKASAND Pneumatic Random Orbital Sander in my shop and
it seems to perform well. I'm a bit concerned a bit about lubricating oil
being deposited on the woodwork during use. I've always used electric
Random Orbital Sanders before. Anyone have long term experience using a
Pneumatic Random Orbital Sanders and it's effect on wood and finish?
