+2 ^^^^ anyone that knows body work knows it's all in the prep! And the "best" painters in the world (auto) will tell you, for professional results, professionally finish the paint (wet sand and buff).
There is another unique advantage to painting a frame versus powder coating it: filler. It's much easier to blend out dings and welds for a fully smooth look under paint than powder coat. There are fillers that can be used with powder coat, but they're much more rare and most powder coasters don't want to do that labor. So most powder coat jobs only cover the metal, and any imperfections transmit through.
So lots of show bikes are painted and filled underneath. This is something the OP can do, and with sufficient coats of paint and clear, can sand and buff it to a perfect shine. And today's urethane clears are very durable, scratch resistant, and can be touched up (even from a can).
I'd encourage you to check back, Twisted, and let's see if the OP
can do a job you're impressed with
