Very nice plane, you did a good job!
I am always fighting with myself if I need to send an order to Eureka Aircraft and have a Banshee kit in my collection.

Yes, the paint issue. Same for me, in the past I preferred to brush the paint, since I was not really willing to step into spraying. Actually, I used rattle cans to spray the paint and then added a clear 2K fuel resistant coat by brush.
Of course that ruined more or less all the effort done before, especially as that clear coat was not really easy to brush.

I made now in summer the step towards spraying equipment now, a small compressor and a cheap spray gun bought from the bay. I was very excited to do my first paint job, but it worked reasonably well and I will continue to do so. It is a new nice challenge in building techniques. Plane is a Aurora 60.
