I've got an old speaker I want to dope lightly for longevity and to make it a little more overdrive friendly. I've googled it and read up a little and it sounds like there are lots of products people have used successfully, but I'm wondering what people here might recommend. Preferably something I can get locally and not have to order online. I've read a couple of things that imply that the stuff speaker companies use is basically just a flexible latex based adhesive and anything along those lines should work. Has anyone tried water based latex contact cement, like the stuff some places sell as tolex glue?
