Any suggestions on removing newglass fiberglass coating. I have a vague
memory that ammonia was useful. And other suggestions?

I've used this on my boat for 6 years now and it does a really nice job.
Unfortunately there is nothing on the label on the bottle in my hand that
indicates what to use to strip it off. However there are clues.

From the label:

Avoid sodium hydrozide based cleaners.
Avoid ammonia based cleaners.
This indicates to me that these substances will degrade the New Glass in
some respect.

From my experience:
Straight ammonia takes _way_too_long_ to be practical. What does work
is a product -sold in Canada- perhaps in the States as well,
called "Super Tuff". It is essentially an *oxalic acid* based liquid
cleaner. Wipe some on, wait about 3 or 4 minutes and then blast the
softened NewGlass off with a hose or a power washer. Works like magic.
You want to avoid letting it sit on unvarnished teak or un-anodized
aluminum for *any* length of time and you should read up on handling
instructions for oxalic acid. This last bit is serious.

From the Newglass2 website:

Removal of NewGlass2
Rubbing compound will not remove NewGlass2. Use our PreTreat to remove
NewGlass2. NewGlass2 PreTreat can be mixed 3 parts water to 1 part
PreTreat. It should be sprayed or wiped on a wet 4’ by 6’ area and
scrubbed with the supplied scrubber. If PreTreat is being used to
remove prior applications of NewGlass2, rinse off surface as soon as
it has been scrubbed. Failure to rinse immediately will allow
NewGlass2 to reattach itself to the surface.

If you have any questions Please call Thom or Jennifer at 800 785 7675

So what is the PreTreat made of?
