Mark you are right you have to hit the stainless with solder first. but it also varies if you use sheet metal or copper pipe I sometimes have to heat the copper up first because it is so thick. And becareful dont heat the stainless too much just enough to start softening the solder to get it to stick too the stainless then you hit your joint and it should flow together. silverbrite solder is a great solder for stainless. Also menards caries a acid core solder you wont need flux with this stuff. But any solder you go with make sure it is at least 95% tin this will stick to stainless better.
