I built a couple of black and tan speaker cabinets. I covered one with tolex from Parts is Parts, and I covered the other with tolex from Mojo. The tolex that I bought from Parts is Parts is better than the tolex that I bought from Mojo. It has a better backing on it and it doesn't bubble at all. It has a softer rubber compound. The MOJO stuff seems to harden a little after it's been applied. As far as their work, goes, I couldn't say. But their tolex is not the greatest.
