Getting the bottom cowl on and off isn't that hard if you don't care about your paint!
I do dread it, but can do it single-handedly since I have the skybolts.
I place a lot of microfiber cloths near the spinner and in the corners to protect the paint.
Remove all the skybolts but one on each side - doesn't matter too much which one, top one or two work.
Release the last one on one side, put the cloth between the cowl and the aircraft, while holding the cowl in place with my "free" hand.
Release the last skybolt, put the cloth in place, and just slowly lower the cowl.
Notice that I forgot to put down the protection for the cowl on the hangar floor, say bad words...
