I have a Marshall JCM 2000 DSL (please...I know...) that needs to have the rearplate glued down.
What is good to use when re-tacking down faceplates/rearplates on the marshalls (and please, no suggestions to use railroad spikes!).
What I have is a part of the rearplate is comming off - I just want to use some type of cement that is typical for a faceplate that can take heat & stress.
Thanks,

I have tried all kinds of glue and have found nothing that will over time keep the rear plate in place. Heat is probably the main factor. I used tiny bronze screws on a 1974 MKII. Pictured was my glue attempt. Sat 2 days and i thought i was done with it. I had used 3M spray adhesive. There may be a glue out there some one else can say has worked for them. I may try marine 5200 on my next repair. Marine 5200 is really great stuff. It needs about 2-3 days to cure good though if you have that much time /

3M adhesive spray is useless IMHO. I've tried it for tweed and tolex and it wouldn't hold either for more than a couple of days without lifting.
Good old contact cement,the smelly kind,works fine.Tolex is another story.
-
I am not much of a glue-ologist: what is the brand of contact cement to use, and is it similar to what Marshall uses?
Also: Plexi I love the high-tech use of that laptop battery for a glueing straight-edge! That will be my next problem to solve - clamping.

I thought that was an old VCR camcorder battery! :icon_biggrin:

Have you considered sponge adhesive tape ?
there are type with a very very thin sponge <adesivetape-sponge-adesivetape> that are very strong, also if exposed to U.V. ray
those tapes are used to attach mirrors in a quick and strong way

what about silicone?
-
I tried some LePage's carpenter's glue. That didn't work, doesn't adhere to metal very well.
-
I use double sided sticky tape . They have all kinds, some of it is almost impossible to get apart . Most I have found get harder with age. I have some back plates going on 3 yrs. still stuck strong . that was with stuff made for carpets.

...or something like this https://www.amazon.com/Gorilla-Epoxy-85-oz-Clear/dp/B001Z3C3AG/ref=sr_1_1?ie=UTF8&qid=1507932527&sr=8-1&keywords=glue+for+plastic+and+metal (https://www.amazon.com/Gorilla-Epoxy-85-oz-Clear/dp/B001Z3C3AG/ref=sr_1_1?ie=UTF8&qid=1507932527&sr=8-1&keywords=glue+for+plastic+and+metal)
make sure both surfaces are clean and free of wax, dirt, oils,,, etc.

This. That stuff is amazing.

Try a thin layer of 2-part epoxy - should work fine!
Or, Loctite AA H8610 - I use this stuff at work to glue plastic to stainless, and have used it on metal-to-metal surfaces and it's pretty much indestructible. $$ though http://na.henkel-adhesives.com/product-search-1554.htm?nodeid=8797944414209 (http://na.henkel-adhesives.com/product-search-1554.htm?nodeid=8797944414209)
