I'm ready to change my oil and ditch the very dented and RTV'd pan that was on the car when I bought it. I ordered a new Febi and laid it down on a very flat surface to check the rim/edge. I'm able to rock the pan a very small amount - much less than a millimeter. It seems with the way the edge of the pan is stamped and drilled for bolt holes that some amount of very minor unevenness is a given - we're not talking about a machined surface here. I plan on using a very small amount of permatex aviation seal on the gasket when I install new pan. Should I worry about using this new pan, and insist on using one that absolutely doesn't move even a hair when placed on a flat glass/mirror surface?

The one on my car is dented to hell but only leaks the tiniest amount.
