I've been riding for about 30 years myself, and I too remember the can wax stuff, but when I bought my first bike my LBS told me to use TriFlow instead of the wax because it would lube the chain better; so I never use the hot wax. I understand that you can still buy that wax though. When I was a kid we just used motor oil in a squirt can for our cheapo bikes and never cleaned the chain...but never had a chain problem!
