A tad off subject, but I need to glue some foam-like...rubber or silicone
spungy material to plastic.
I have seen Silicone seal or RTV by GE, Dow Corning and DAP. Does anyone
know if these are all the same? Is one Acetic acid based, and the other
methanol based? Is one better than the other?
Or, perhaps can anyone suggest a better adhesive for this purpose??
Thanks for any suggestions you may have.

There's all sorts of silicon sealer stuff these days. Some is still
acetic acid based and isn't very popular around some metals but that
doesn't sound like an issue in your case.
Weldwood Contact Cement sounds like another alternative for you.

I would agree with the contact cement approach.
Follow directions- contact cement works through cohesion not adhesion.

GE and Dow both make a couple hundred different kinds of RTV. Some are
acetic acid based and some are not... the ones that are not are specifically
sold as being for electronics use most of the time. They are available in
different viscosities as well, from very thin to very thick, and also in
high temperature red versions. DAP only sells an acetic-acid based type
for construction use.

If you are using it on nonmetallic objects, the cheaper acetic-acid sort
is fine, because corrosion isn't an issue.

What is the plastic? And is the rubber actually rubber or silicone?
RTV is actually a very poor adhesive, and it shears very easily. But it
is an excellent fill material so if you have open-cell foam, it will grip
it well.

To cement foam rubber to most things, I would tend to use contact cement
(Super 77 or equivalent), because it is a much stronger adhesive and also
fills voids well. Not as flexible as RTV but still very flexible.

I'd go to a hardware store & ask for some weatherstrip cement. That type
of job is exactly what it was designed for.
