I rebuild a lot of cylinders, and the hot water trick does the job just fine on the seals your talking about. Once heated, they usually go on easier of you manually stretch them a bit before putting them on. The trick of using the hose clamp, with something to protect the seal from the ends of the clamp works, but if you've got a piston ring compressor, it works even better.
One thing to make sure of is that the hard seal has shrunk back down to where the back edge is below the surface of the piston before trying to put it in the barrel. If it's not, it will try to jump out, and it's easily damaged if your not careful. I'll often leave the clamp/ring compressor on the piston until it goes into the bore far enough that the seal can't jump out.....basically just like loading a piston in an engine.
Beyond that, as you've seen thus far, it's not rocket science, it just takes a few tricks of the trade to make things easier.
