Where can i get ribbed aluminium or steel sheet?

You're right, interesting to see how well its built and the detail Tamiya put into it!
The vertical panel lines make it easy to conceal the join though.

The Prime trailer lines run horizontal along the trailer, with no obvious seams.


And yeah, the bottom sheets are easy, i can buy aluminium sheet cheap anywhere. The top i'd go for a nice bit of stainless though. At least plain should be far easier to get!
