Thanks guys, I'm glad you like it so far
Bit the bullet and started on painting it finally. First I did a rust layer with different colors of primers until I had a mix of colors I was looking for. Going for a bit more weathered look on the body like in my inspiration pics. Doesn't have to be perfect as most of it will not be seen anyway:
First try on weathering and the body color on the jerry cans, works quite well imho. I sprayed the whole can with hair spray the added the body color on top. Then went over the whole thing with a wet tootbrush until I got this look:
Scary bit was doing the same on the body
Turned out pretty much like I had visioned it, I like it! Now adding scale items and details, there will be some yellow details on it (like door handles, race numbers on doors etc) to give some contrast on the worn out greenish paint.
Going for a shake down run today, let's see if it's driveable?
