"Spotless stainless steel" reviews?


Any direct or first-hand friends' (you saw it personally) experience with
"Spotless Stainless Steel" (http://www.spotlessstainless.com/) here?

Wrestling with passivation issues and rust removal-and-protection for our
on-board stainless, we examined all the usual options; citric acid (the
active component here) seems to be the most envrionmentally friendly,
least
dangerous, and perhaps the most effective.

Phosporic acid, recommended by a friend who'd had all his new stainless
work
done where that was the pickler, seems to only take off surface rust, and
actually promotes rust in the end on stainless; worse, it attacks
chromium,
not a good thing for making stainless stay bright. Worse still, it's
nasty
for the marine environment, making phospates. It's actually usually used
in
paint prep for non-stainless steel applications.

Nitric acid, while effective, is very user-unfriendly and not so great to
the environment.

So, if it actually works as the company-sponsored reviews state, it looks
like it would be good for us to use on, in particular, the bow roller
welds
mentioned in the St. Augustine log, as they look perfectly awful.

Interesting stuff. I'd imagine you need to protect the fiberglass from it.
In one of the pictures on the website, it looks like it foams a bit, which
might keep it from running.
