I am sanding bare metal with 80G so I can apply epoxy. I am using Dura-Gold PSA on an old-school 4" hard rubber hand block, the one with the teeth, and 6" PSA discs on my DA. I am not sure when to replace the paper so I am doing about half a panel per DA disc or sheet on the hand block.
DISCLAIMER:
I bought the Dura-Dold paper before I knew better so I plan to usr it up on the metal sanding. From now on I will be using Sunmight and Benchmart Abrasives paper.
The 2 pictures below are from DA sanding at the point where I replaced the disc. Is the scratch on the metal good enough? I have no previous experience or point of reference,
