Yes it is.
You can congratulate my friend Jérôme for this great model of a wh40k Basilisk. I tried my best to paint it and make you forget it was made of MDF and cardboard.
Rust layer and Worn Effect varnish
I have to say that I wasn’t really convinced when I started painting it. The end result isn’t bad actually, I think we could almost forget it’s made of wood and cardboard, don’t you think?
