Which type of sander should I buy, to touch-up the skimcoat after I
have spread it?

Random orbital, belt, vibrating pad?

Please reply urgently. I am buying the sander tonight. I appreciate
any input you have.

PS - I cannot stop the group from pontificating at length on my
situation. But please: if you must type 1000 words on the wisdom of my
project, at least throw in some advice about the sander.

Dunno what you're calling skimcoat- assume some sort of patching/
leveling
stuff for divots you'll pull out of the ply.

Given that, suggest you apply any such stuff sparingly, with wide
knives. If
advisable, in multiple thin coats.

My first guess as to sander would be a 6" PC ROS (with vac
connection),
and 60-grit. Combo I use for rough work.
