Striving for perfection! Great thing is you are at the point where I'd start getting bored and slack off on the surface prep steps, you keep on truckin' 👍

You should check out the mystery box of PSA rolls from Klingspor. I needed some wide 120 so I ordered a roll (about $9) and to fill out the order I got the mystery box for $12. Not only did it include the same roll I had bought separately, it had a dozen other same and wider rolls of various grits and abrasives. Basically a dollar a roll. Now I never have to spray glue paper to sanding blocks and don't hesitate to refresh the paper since it is so easy to replace for a few pennies.
