Workbench top
Just starting my 7A build. After completing the practice projects, I noticed a lot of surface scratches. Should I line the top of my work benches with any type of padding to help prevent these during the actual build?

Some do, most probably don't. If you're going to paint the exterior, all of the skins will need to be scuffed before painting. If you're priming the interior parts, you'll also probably be scuffing them to get the primer to stick.

I use that white melamine-coated particle board from the big boxes for a table top, with no scratches. It makes excellent work table tops.
But I also leave most of the blue on the skins - small parts get it totally removed, of course.

Foam Pad
I like to use tool drawer lining pads or other thin foam rubber if I need to put a skin on the tabletop. The tool drawer liner also keeps parts from slipping.

You can also use some rug non-slip underlayment of this kind. easy to shake off after drilling.

I just used some old bath towels laid down on the workbenches. Easy to clean, just throw them in the washing machine.

Draping moving blankets over the bench works well too ...

In the 70's it was recommended to use cardboard with one "side skin" absent. The chips from drilling would go in the cracks and minimize scratching.
Then I "found" (real) astroturf. Not the indoor-outdoor grass, the original, like a small cup of fingers, about 5/8" tall.
Excellent weight bearing and nil scratches because the chips have great room to fall. [Link to Amazon image]

Excuse the link if it's not up to par. First time trying an attachment and I'm late for dinner!

Same here. When the wood surface gets rough, I spread spackling compound all over to fill in the holes and cracks and run a random orbital over. Smooth as silk.
Don't overthink. It's the enemy of completion.
