Pre-shave prep the same on second/third passes?

thanks all. I'll just have to see what works for me. I haven't been able to really get a routine going because a. My brush had to ship from China, so it's taken nearly a month to arrive, which it should be doing this week, and b. my razor had to be sent out to be honed again. But I have a feeling just re-applying rather should be enough to comfortably do a second/third pass. I like the idea of a heating pad to keep the lather warm... I was trying to avoid any "modern" technology in order to keep the shave as authentic as possible, but would also like to use a can of compressed air in order to eliminate all water from the nooks and crannies of the razor... but I just rambling now. Thanks all for the input.
