Help with Ambroid EZ Mask

Well I opened it and it was a very gunky substance. It wouldn't be able to be brush because it was not a liquid for some reason. Any ideas why this happened and how to fix it?

Haven't ever used that brand of mask, but based on other liquid masks I've used, I'd say you have an expired bottle.

Throw it away, It looks old. Mine a very smooth consistency but thick and can be easily brushed.

Thanks for the replys!

I got some humbrol maskol, and this can be re-thinned with water. Not sure if this is the same, but anyhow, it's cheap may as well buy some more..
