Just also bought a used Reliant 13" widebelt sander, what grits do you guys use when lam grinding? Gonna buy from Supergrit
60
60 is what I use , Smooth on says 120 for smoothest I believe , and if you get down to 40 you can see some sanding marks thru the glass has been my observation...
60 with Alum... 80 with Zirc...
I use 60 for everything.
Well 60 it is, thanks men
