How to best get super smooth?

I’m a pretty hairy guy and personally, I cannot stand it when I want to feel little. I see pictures of many ABDLs who are baby smooth - particularly referring to their diaper area, belly, and thighs. Whenever I try to shave my thighs especially, I just get a bunch of red bumps and it hardly makes me look smooth.

Are there any tricks I should be aware of? I haven’t had much luck with Nair, but I’d be open to non-shaving options.
