I used MS powerpoint for the basis of the Aileron trim decal. I printed it on a decal paper and then applied 3 coats of polyurethane clear coat to seal it. After drying, I trimmed it to the correct size and then saoked it in water in order to remove the backing sheet. I then applied it to the center piece and adjusted the position. I let it dry out for several hours and then I applied 2 more coats of clear polyurethane on the whole part.
