I hear you re the colour and heat... but most folk here don't venture far in the full summer. There will be days when we wish we had a white truck, but the plan is not to stay in Oz... We'll do a lap in winter when it's a little cooler, then either ship to NZ or Africa.
Re the paint, I believe it to be a two pack paint.. It's hard, and he needs a special filter, and when we do the whole body, the workshop will have to be closed, and a fancy extractor with filter will be set up in the small door. Had I done it, it'd have just been a simple equipment enamel!
