+1 on Rema != rubber cement. Whether that matters is up for debate but in my experience you can tell the difference on how the patch adheres to the tube. In fact, since Rema is easy to find (check ebay) I don't bother with anything else and just bought a kit with about 100 patches and a huge tube of solvent. It was the price of about 5 tubes but should last the rest of my life.
