@KingDeadshot Sweet! thanks again buddy!

@KingDeadshot Thanks! If you don't mind my asking, how were you able to do that?

@Gestour Thank you again for the info. I just checked the Eucl3D website and they say they do this: "Models are then infiltrated with an epoxy to make them significantly stronger and make the colors pop out! Once dry, they are covered in a thin layer of wax to help preserve the prints". Here's the link to that statement: http://eucl3d.com/pages/how-its-made

Here are a couple of pictures of the model I just received:

It definitely feels a little sandy, but then again, I purchased the smaller, cheaper version.

Other 3d printing companies glaze their sandstone prints in cyanoacrylate, and then seal them with epoxy resin, by hand, with a brush, which is a painstaking process.
Spraying it with a clear enamel paint is just not a reasonable option. It's notorious for running, yellowing, cracking, falling off. Many valuable collectables have been destroyed in this way over the years, it's has been proven not to work. Enamel clear coat is only good for sealing other enamel paint.
The best option is to put it on a shelf and not touch it, and if your friends have to touch it, get better friends, or make them wear white cotton conservator gloves.

@Chemicalau

Thanks @Gestour :)
I'm planning on just putting it on a shelf, but I can see a friend grabbing it. Also, a glaze may improve aesthetics in addition to protecting it. I'll pickup some Epoxy or Rust-Oleum per Coen1888's suggestion. Thanks again for the suggestions guys!

Epoxy.
But the best thing would be to put it up on a shelf, and leave it alone... It's not a toy.

I think this May work

@Chemicalau Your welcome!

@Coen1888 Thanks buddy! (also thanks for the upvote!)

I don't know but I will try to help.
