Hi Stuee,
It's the first time that I have tried this paint and as Gav points out - "Roger" is like a vampire and hasnt seen direct sun light yet.....
So I can't honestly answer your question on the paint / UV attributes.
I didnt use a primer although I usually do. I used my electric drill and red plastic disc and thoroughly cleaned the surface first, then metho and a clean rag. And then another clean cotton rag..
I suppose only time will tell!
Cheers,
Tom.
