Re: painting the tank
Paintwork is a whole topic of artistic adventure!
You can go from brush painted boardtrack styled work to steam punk to magnificent air-brushed fantasy...
You Should prep the tank well by sanding, and you Should apply decent primer, and you Could use model paint...
Best to use a fuel proof product!
Spend a little time reading the paintbooth threads and see what the felows are using currently, for results you would like to see.
My goal is cheap, reliable, personal transport, below the tax collector radar. Fun counts for a lot!
