You could get some Klass Kote. Basically the same as the old K&B Hobbypoxy.
I painted my last plane with Klass Kote and really enjoyed the paint.
I covered the painting process in my thread but here is a direct link to the page with the finished plane.

I can also speak highly for the comany too. Great to do business with them.
