Hi Brian
I asked Bavaria a few years ago for Pantone colour codes. Here's what they said...
"the gelcoat color code is at Bavaria 44 , 2003
for white gelcoat : RAL 9016
and
for blue gelcoat : RAL 5013 ."
I was looking at painting mine, but they polish up reasonably. Just doesn't last too long.
Several others on this forum have had plastic stripes made and applied them. Not sure of the material, but I'd imagine whatever they use 'wrap' cars would be good.
Let me know how it turns out. I'll have to do mine soon.
Cheers
Bob
