any specific brand that's better than others that can be bought at a Lowe's, Home Depot, etc?

Home Depot sells a spray adhesive made specifically for vinyl and rubber and it's made by 3M (it says "rubber and vinyl" right on the can). Tolex is a type of vinyl so you're good to go if you use that. You could also use contact cement if you'd like. Home Depot sells that too. I couldn't find either of them at lowes around my area. If you're doing a 412, you'll need two cans.
