You can usually buy brush top cans at your local auto
supply store, Camel Brand is still around.
Also we all probably now realize that the non flamable cements are poor (but wont burn down your garage)
I think any tire cement is compatible with any patch. I usually buy 10 small kits at a time and keep them with a spare tube and tools in various seat bags that I use on different bikes. I do keep an 4 ounce can of cement of the work bench
