60's classic car paint finish

[Memnon]

Just reading a review of a 60's Classis .... it describes the paint finish as:
"the body receives two coats of primer and three coats of final finish, all rubbed down by hand, followed by underscaling"

What is 'Iunderscaling' ? ..... Google shows up nothing.

Typo? Undersealing?

It’s probably a typo, meant to say ‘undersealing’?

No don't think so as its referring to the gloss paint finish.

Maybe .... article was referring to paint finish .. maybe just bit of poor writing.
