Hey Paul,
Will Seal All work for rubber to steel? The HPM-40 woofer gaskets that I just did seem to not play well with the P/E glue.
Yes, and very well. It is great for disimilar materials.
I don't pretend to be an expert, but I have about 25 different adhesives on my workbench that I use almost daily. And they are all different, best suited for different purposes. I have thin, medium, thick, and gel CA glues. I have 5-minute, 15-minute, 45-minute working time epoxies. I have several different types of epoxy putty.
I have three different SBR adhesives. That is Styrene Butadiene Rubber adhesive (according to the manufacturer's rep who I spoke with on the phone). E6000 is the thickest. Aleene's Platinum Bond 7800 is a little thinner, more solvent, viscosity about like epoxy. Seal All is the thinnest, viscosity about like plastic model glue.
Gorilla Glue (I have it, too) is a polyurethane glue that expands as it hardens. It is best used for wood, and requires clamping. The expansion forces it into the pores of the wood and you can get a tremendous bond.
I have three different types of white glues (aliphatic resin glues). Three different types of stick shellac glues (pads on woodwinds). And more.
Anyway, there is no one glue good for everything, or I wouldn't have all that cluttering up my workbench.
There is a glue by Wilhold, RC56. It was in hobby shops, and I suppose other sources. I used it for RC model airplanes. It was great for gluing plastic canopies to "Monocote" or other iron on plastic films. It looks like white glue, but dries with a slight flexibility. Great bonding to plastics. Not as tacky as Aleene's Tacky glue. This would be good for dust caps and perhaps the gaskets, too. But the set up time is too long for working with surrounds.
Back to rubber surrounds and poly cones... I think the Seal All would be best for this. It dries very quickly, too.
About bonding and strength of SBR adhesives (E6000, Aleene's 7800, Seal All) I'd like to refer you to one of my articles:
