Hi All I normally use water based poly, but this time (for the first time) I'm using nitro to finish a guitar. I'm reaching the point of final sanding and I'm very nervous about wet sanding. If I wet sand with water I'm worried about grain raise and sanding with mineral spirits really doesn't appeal - I'm pretty sensitive to solvents. I then came across this: This guy says that with modern no-load abrasives, there's no need to wet sand, that you can dry sand. Any thoughts? Any idea what sort of paper he's talking about?
