Just to double check before I make a hash of things...
When dry sanding something, a sheet of 'wet and dry 600 grit' will effectively have exactly the same amount of abrasion as a sheet of my 'dry only' 600 grit sandpaper?
doesnt work like that..dunno why
400 dry paper , is roughly same as 800 wet n dry
Confused now :S
Are you saying using 400 wet / dry paper in a *dry only* scenario, is it not going to give the same abrasion as 400 grit paper specifically for dry sanding only?
