Bought a jar of mud, Dry as a bone! Can it be reconstituted?

Which one is this ?

It was European Wet Mud rough texture

What's the number , I'm just wondering if it's enamel or acrylic ?

Acrylic, Number P503

You could try a little bit of lacquer thinner , or if you just bought this bring it back .

Did you try to email mig ? Now you my curiosity stirred up . Never had tried this product and it does look good .

I did try the laquer thinner, and it did help, but it also turned the chunk I experimented on into a fibrous black mass. Will be good for building up an undercoat or shape, but will require additional painting to be acceptable for an outer effect. I did not email MiG having purchased this online from a vendor in the U.S. I did ask the opening question on their facebook page with no responses as yet.

Get hold of the seller maybe it's not too late . Did you pay with PayPal ?

I did contact the vendor, they shipped a replacement at no charge.

That was nice of him sir .
