Krylon works well with no clear coat, however the aluminum and chrome colors are not fuel proof and will discolor with raw and hot fuel. I have not tryed any kind of clear coat yet as I am not sure what is compatible. As long as you are not using those colors it should work great.
Yup.
One key thing with Krylon is to give it a LOT of time to dry.... over a week before you fly the plane.
I have not applied clear coat over the paint on mine, when I've used gloss Krylon, the end result looked pretty smooth, provided I applied light even coats.
