I'm with Tim on this one, our JP4 (XS186) is returning to her original grey with dayglo this year (College of Air Warfare badges too, now that's a unique scheme!).
We have tried some original fablon dayglo, horrible to apply nicely though , so although more original, we are painting our dayglo on, having found a perfect match from a German company with a non fade 10 year guarantee, that's German goods for you .....
