I decided to paint my HP-24 myself. Overall it turned out nice and
saved me a whole bunch of money, while not "perfect" it will do just
fine. For a guy with a CostCo hoop house and a Harbor Freight
conversion gun I'm pleased!

My question is: how long should I wait to apply protective wax to the
airframe? And.................any suggestions which "wax" or product
to use?

I never did wax my Apis after we painted it, and later in life it
started developing moisture blisters, while not as heinous as the
blisters I've seen on other painted sailplanes at my field, they were
rather horrifying to see just the same. My hopes are that putting on a
good protective barrier should help with this.
