Speaking of Roundels and the like,I have bought some of that printable vinyl for decal making.I got both clear and white, for obvious reasons. Problem is, my canon printer ink,though producing excellent results,seems to fade badly in sunlight, at a rediculous rate!The black seems reasonable, but the dark blue/red roundels I fitted to my warbird are now sky-blue and pink! (PS. they were fuly sealed prior to fitting, and again once in position, using that RS clear sealer stuff) Does anyone know if there are inks out there to withstand uv fading? Please advise me ,as I have further plans to use this nearly £1 per sheet stuff.
