Finishing DA and Inline Sander

The air inline sander is a great tool for quickly cutting down the new epoxy based fillers. I use 80 grit paper and very frequently, smack the paper to clean the dust off. The paper lasts a lot longer this way. I take long strokes and sand in constantly alternating motions: vertical, horizontal, diagonal. The catch is that the inline sander is good for mainly flat surfaces.

I alternate between the air sander and a finishing DA sander because both are used on flat surfaces and it is easier to get a uniform finish. The finishing DA sander is usually considered a woodworking tool and not an autobody tool. It works for me. This way, the area starts to conform to the rest of the body shape. I constantly feel the surface of the work to feel for high and low spots.

I've found that the sanding dust can give false impressions of low and high spots so I constantly wipe off the surface. I've also found that after sanding for a while, my hands lose their sensitivity to the surface so I take a break and go do something else. Must be the vibration of the sanders..
