Thanks, Bill.
I've stripped off the bright white paint on the panels, as I quite like the "accidental" creamy white on the tank, so that's a keeper. I'll reapply the black and put the panels on to see how they look, just black. My worry is, that, with a black seat and frame tubes, it will all splodge into one big, black shape. Should that happen, I'll go over the panels with white and clear and get the creamy effect, if not straight away, then in a year, or so 🤣
Here's a charismatic professional, showing us how it's done with proper paint and equipment on a GB500 tank, I think. Like a true pro, he makes it look really easy 😀 You get a brief glimpse of the cafe-racer at the very end.
