Used primer to give it a more stoney color, but found out it was too brittle. It started to crack and flake off, but I only rubbed off half of it.
I imagine it won't have that anymore after the Teonn weekend :laughing:
While I remember there’s a spray called “Metal Hammer” that you can get from Mitre 10 that does a very nice marbled/mottled mettalic effect effect. I’ve used it on corflute and cardboard and closed cell foam and it looked good on all of them.
