I've built three amps, all covered in tolex (or off-brand material). I got the hang of it with help from Uncle Doug's videos. A few months ago I saw Benson's gorgeous amps covered in cotton fabric, rather than a vinyl material. For my latest build I decided to give it a shot. I went to the fabric store and bought a yard of this geometric mid-century-looking fabric. I cut a few test pieces and started testing glues. I don't see how the contact cement + spray combo could work since the fabric is porous. I tried Gorilla Glue spray, 3M 77, and Mod Podge. The 77 was bad, the next day I could peel the fabric right off. The Mod Podge held well but bled through the fabric like I thought a liquid would. The result looked a little uneven, because the glue pushed back through the fabric more in some places, even though I rolled it while the glue was still wet. The winner was Gorilla spray. The fabric went down flat, and had really good hold the next day. Then came a finish. Benson says their amps are "brushed with lacquer." Well, I tried that. It really took all the clarity out of the pattern. It yellowed way more than I thought it would (it's just clear gloss lacquer). Wondering if anyone has any experience using fabric as a finish? Any ideas? Would a gloss poly give me the same look in the end but come out clearer? Is the loss of clarity in the pattern just something I'm going to have to deal with?
