Sorry if this is a bit off topic, but I have a
“finish” question.   

Many years ago the former SWMBO and I purchased a
maple worktable from Williams Sonoma.  It is not a
true butcher-block table, although most people take it
for one.  It is made up from "2 by" material glued up
on-edge.

Anyway, for upkeep Williams Sonoma supplied a green
scotchbrite pad along with a small can of urethane
paste to apply when needed.  Since the table has
functioned only as a storage table and now a breakfast
table it has not "needed" very often.  I like the way
that the finish goes on and the hard satin luster that
it leaves.

So, what exactly is a “urethane paste” and where can I
get more?  The information on the can is as follows:

Taylor Woodcraft
121 “TM” Finishing Paste
with extra urethane

It also has an "NSF" logo (NSF Testing Laboratory, Ann
Arbor, Michigan) on the back.  

I’ve searched the internet for Taylor and 121, etc.,
to no avail.  Since I understand enough about finishes
to be dangerous I thought that I would ask those with
greater wisdom. 

Thanks in advance.
