So, the material came in for my budget Fender Stage 160 recover. Speaker cloth is vinyl coated fiberglass and went on easily with some double sided tape and staples. I have a little fine tuning to go on the corners of it, but I'm really happy with it. The fabric for the cabinet is heavy upholstery cloth, but has no backing, and is probably not quite as rigid or tightly woven as amp tweed, FYI. I bought Titebond II and 3M77 glues to test some of the fabric for the amp on a piece of wood. Results were less than spectacular. I tested them at lunch today, roughly 6 hours ago. The Titebond II is now holding on with a death grip, but there were spots where it bled through and has dried yellow. Don't want that. The 3m77 was sprayed on the wood sample and the cloth, and I waited the requisite 30 seconds for it to tack up. It took about a minute instead. I then pressed the cloth onto the board and firmly rolled it out. I was happy to see that some repositioning is possible. However, after 6 hours, the hold is not quite as strong as the Titebond II. I can peel it, though it's a firm hold. I will say, when I ripped the tolex off this amp, it peeled off relatively easily. So maybe this isn't even a problem. Questions: So, does the 3M77 hold get any stronger if I wait, say 24 hours? Clearly I'll find out tomorrow at noon, but just asking. I plan on coating this with clear shellac and then coating with wipe/brush-on satin poly. I know shellac isn't known for its strength, but will it or the poly add any more adhesion to the wood (actually Fender particleboard)?
