Yeah, I've been using Dura-Gold brand wet sanding discs from Amazon. I've never been a body guy, so maybe I'm not keeping the paper wet enough and I'm getting a booger drag over my work area (approx 2x2 ft at a time)? Or maybe the quality of the sand paper I'm using is too poor? I'm using a hand spray bottle with water and a drop of dish soap to wet the area and the sand paper. I use the orbital sander and re-wet the area and rinse the paper with the spray bottle when I feel the sander bog down / drag. Sometimes this is on the first pass, especially if the sanding disc is brand new. Am I waiting too long to re-wet/rinse? If there's lots of slurry on the work area, I'm wiping it off with a micro-fiber towel and rinsing/wringing that out when it gets loaded with the slurry.
I'm using Aqua-Buff 1000 followed by Aqua-Buff 2000 on wool pad / rotarty buffer on a low-ish speed (2-3 out of 6) with some (10 lb?) pressure applied to the buffer. Separate pads for the 1000 and 2000. In some of the areas where I did 500 & 1000 grit passes, I went ahead and test-buffed and could still see some of the sanding scratches, which is why I went back and did 1200 and 1500 over the entire area.
As said, I'm not a body guy, so I'll probably just live with what I've got if I can't get the sanding marks all the way out. 99.9% of folks won't know they're there, but I'm all about learning to be better.
Any recommendations on a specific wax after I finish buffing, and how to apply that wax (buffer/wool or foam pad, or by hand?)?
