I have read some good things about plasti-kote laquer out of the can around here. Tried it and it seems to work quite well. I have yet to fuel test it though. It should be OK with mild fuels.

No orange peel or overspray whatsever. It's sold off the rack at Pep boys, Carquest, and Advance auto. They also sell good primers in good colors.

One thing that may help you apply the paint is the little spray handles that clip onto a spray can so it's easier to hold/use:

I've seen them in auto parts places as well as the paint section of Wall-mart. They are very convenient and reusable and cost about $3.

I have a couple of scale gliders that I coated in plasti-kote enamel - didn't need to worry about fuel and want the toughness of enamel. Bright white, but could not avoid overspray problems on either plane. Seems that a wet-sand with 1500 paper will take care of that. I'm leaving them out in the sun when I can to help get the paint hardened up.
