Sounds like a good idea. As long as the paint is flexible enough to follow the contours of the decal. Be interesting to see how it goes.
I did manage to find all the decals that I need from other kits in my 'to do' pile apart from the Motorcraft and Istel Tourist Trophy ones. The Motorcraft ones I have found on a Ford website (does anyone know if they were Fluorescent red, they look like they might be in some of the pictures I have seen) and I think I may actually have the 1986 TT race programme somewhere, just have to find it now......
Also don't know how I will do the Eggenberger windscreen one yet either.
