I need an epoxy that will be able to bond stainless steel to PVC or polycarbonate and will be able to stand up to a decent amount of vibration. Anyone know of a good product?

Why did I put delrin? I mean polycarbonate. oops.
There is this great product--a pressure-sensitive uni-directional bonding strip coated with polyethylene--that should do the trick.
along similar lines as mtn, but it might actually work - look at the 3M VHB double sided foam tape - the kind they use to stick plastic auto emblems to painted metal. We used it in the sign biz for plastic/baremetal adhesion and it works really well IF the surfaces are clean prepped AND you don't expect it to hold a lot of weight.
What about Loctite 380 Black Max?

two thoughts
1) talk to guys who restore corvettes.....they have to be using some strong glue to hold fiberglass panels to hydro-formed aluminum chassis.
2) primerless urethane: most windshields on modern cars are glued on, and that's the stuff they use. I've heard tell that it is REALLY strong. You can buy a small tube of it at your local advance autoparts and play with it to see if it will work for your purposes
<== not a 'vette guy

I think so...."repair" would have been a better word than "restore", though. Even before the hydroforming, though, the same issue existed; the cars have composite panels and metal frames.

Oh, and while I'm posting links, here are some for primerless urethane window adhesive.

More information is needed. The reason your question cannot be answered is that I can't tell if you're objective is to do something impossible. Or not.
"I want to glue one end of a 1/4" stainless steel rod to a piece of 2" thick PVC plate. It will only be loaded 50 pounds" - won't work. Install a threaded insert in the plastic and put 1/4-20 threads on the rods and you're set.
"I have a bracket folded out of .060" stainless sheet. It has a flat base about 2" square - I want to glue this to a 1/4" polycarbonate panel. The bracket will see 5 pounds in a bending moment at 2" above the adhesive" - this can be easily solved.
I've specified applications for this sort of thing on solar energy (photovoltaic) and biotech consumable products, and there are many drivers governing the adhesive selection.
Answer the following and I can help w/ the adhesive:
The size, shape and profile of the stainless steel part
The size, shape and profile of the plastic part.
Is it PVC, Polycarbonate, or something else?
Does it have to be PVC or polycarbonate?
Operating temperature and min/max temp range.
How frequently and how quickly will it be thermally cycled?
Accurately describe the physical loads - this it probably the most critical factor. Tension, compression, flex, peel, shear, bending.
