It is quite possible Randy, this is from one of their web-sites
(they have more web sites too, depending on the market):
"Zep has a solid presence throughout America and in the international marketplace, reaching into every major city in North America, and countries around the world on five continents."
While we are on the topic of ZEP, I found this link:
Stella Blue - 2008 Haulout
That says they used the ZEP floor stripper and Bar Keepers Friend to remove the gel coat oxidation, I quote:
"I watched the wax bake onto my topsides.
It left a horrible buildup, that I'd
tried to remove for the last two years.
A wonderful woman on the next dock over
suggested that I use Zep Floor Wax stripper,
following the directions and
using really hot water.
It worked incredibly well, and also
chemically removed all the gelcoat oxidation.
It took two iterations of stripper,
scrubbing with a soft abrasive
and a white 3M scrub pad.
But it worked really well,
and my topsides look great again."
