Acrylic. That's the magic word.

If it dries waterproof but strips off with Ammonia, that's the stuff you
want.

Reading from my bottle:

Future Premium Floor Finish

"Long Lasting Shine Tough Acrylic Protection"

SC Johnson A Family Company

On the back of the label, catch phrases like:

"Is a tough acrylic floor finish that contains no wax"

"For No-Wax and regular floors".

Then there's the "helpful hints section"

"First time users should thourghly clean their floor with a solution of 1
cup ammonia and 1/4 Armstrong
floor cleaner in 1/2 gallons of cool water".

The key word there was Ammonia.

Track it down, find it, borrow it from your wife or mother. I think you'll
like it.

Works great in a fine tip technical pen for touchups for other resist
methods too. Easier
to use than a sharpie. The only drawback is it's clear. But you can color it
with some
machinist's blue or inkjet ink.

later,
Larry E.
