It had to say it crossed my mind when I saw hippy's (though his van is black afterall I guess), could get toasty in the summer. I am going to try and keep the same basic boring grey. These jobs always turn out more work that you initially think. Just a small area of spraying is now dictating my Bongo use over the next days as I don't want to re-mask and of course the moment I want to spray the wind picked up !
And I also notice surrounding chips/rust spots in the same area which means another day I will need to do some spot touch ups as well. Keeps us busy.

Been thinking about the spraying a bit.
Going to be honest I am not keen on the finish from roller-ing. On the other hand not keen on the massive labour/logistics involved in 3 coats of spraying (sand, prime, top coat, lacquer) Primer leaves a rough grey surface, I wonder if that would be ok to just lacquer over or not without sanding, that would be a kind of textured coat. Anyone know?
It seems primer is just acrylic matt grey paint. Is that a fair assumption ? A silky smooth finish on the roof is not essential, I don't feel the desire to sand it down after the priming.

Primer and 2 pack lacquer would probably give you a perfectly acceptable and durable finish. Primer on its own is a no-no I think: too porous. A good 2 pack (gloss) lacquer should leave the finish looking wet high gloss with no need to wet and dry I reckon. See what Stuc says.

That might be a bit pricey but I do understand the logic of what you are saying Mike. At leasta very decent quality normal lacquer I wonder if I can buy the Hicote "Body Shop" UV resistant lacquer more cheaply in bulk. I will investigate.
You can get the Hicote Bodyshop for £5.99 a can when bought in packs of 6. Will check for lower cost 2 pack options.
Have to watch out a bit buying "2K".... check the red print:
"
ATTENTION PLEASE BE AWARE THAT THIS IS 2K LACQUER WITH AIR DRYING 1K CONVERTOR NOT CHEMICAL DRYING ACTIVATOR
AND IS NOT PETROL RESISTANT"

Before I proceed with the whole roof I will try and do a spot on the back of the roof to test the finish out.
