When you say painting them on is to expensive. I have to ask. I use to use the stick on vinyl numbers but later found the price for the stencil vinyl stickers cost the same amount. Now I order the tail numbers in a vinyl stencil, stick them on and paint the numbers on with a very small and cheap spray gun. Peel off the stencil and I have perfect painted on tail numbers for not much more than the cost of the stickers. It takes very little paint and can be done outside on a nice day.I mask off a few feet away from the numbers and then cover the rest of the plane with sheets. The trick is, you have to remove the stencil within 30 minutes of spraying the paint. If you have any creep past the lines you clean it up with q-tips dipped in paint reducer.Just my 2 cents.
