Furball Aero Design is a new decal company. They have teamed with Detail & Scale who I have admired and trusted for many years, to turn out interesting and correct decals and marking schemes for 1/48 modern US aircraft. They also have vinyl mask sets for those kits.
This decal sheet consists of all of the markings you would need to do two Blue Angels aircraft, either two TF-9s or two F9Fs, or one of each.
The Blue Angels flew the Cougar from 1954 to 1957, when it was replaced with the F11F Tiger.
The decals are printed by Cartograf of Italy. I put Cartograf as the industry standard for quality decals. My basis for this is toughness of the decal film and the fact that it only takes about 15 seconds in the water for even the largest decal to come loose from the backing. Even I can get a decent looking set of markings using Cartograf.
