So, how did they turn out?
The first thing to point out is that they come with a HUGE base built in i.e. on one side of the truck the base sticks out at least an inch; on the other, at least a centimetre. I'm not sure why they come like this, but they do. Here's the picture from their website that shows what I mean.
The other thing the picture shows is the holes in the resin: you can see a big one on the door, and lots of little ones in the main body's wooden panels.
Well, I could do something about the bases - snapping them off to a decent distance from the tracks wasn't too difficult - but I decided to ignore the resin bubble holes: far too fiddly to fiddle with.
A black undercoat was followed by an all-over coat of a medium dark grey. I then dry-brushed the canvas top in a lighter grey, then dry-brushed both canvas and body with white. The windscreen and other glass was dark blue and then my (only slightly successful) attempt at a glare effect. The tracks were my usual gunmetal covered with flesh wash. Here they are:
