That's my experience so far building a -7, though admittedly I learned most of the skills building a -6 with my dad many years ago. Things like hanging wings are far easier with a couple of helpers, but don't take that long at all. I had some coworkers help out getting the wings on and off, and it only cost me about $20 in beer.
I've found that the required skills for riveting the few places that I can't reach myself (some parts of the wing skins, lower fuselage, and tailcone, so far) can be taught in a few minutes, assuming your helper can follow basic instructions. My wife has helped with the riveting; I've also had interns from work, my brother, and my sister-in-law drive a few. It's easier to have them run the rivet gun than buck, IMHO.
The only other place I really needed assistance was building my engine from parts; I had an A&P friend with Lycoming overhaul experience help me with that--though admittedly most people just buy an engine. I just had to be difficult
In short, the "second person really required" time will be well under 1% of your total build effort. Don't give up on building just because you might need a second pair of hands for a couple hours.
