However, if you go to an art supply store and look at the thicker acrylic media and clear gesso, you may find what you need. A lot of people use those for collaging heavy or thick objects, so that they will not come off. So you will find other uses for those products anyway.

Again, you would have to compare carefully to see if they are actually cheaper in the long run.

Do you need something that is waterproof?

Have you tried Golden gel medium?

If you need something that stands up more (is more 3D), how about using or any of the stiffer clear acrylic media (especially those by Golden) or a clear gesso?

I really like Diamond Glaze (or is that what you meant by Dimensional Glaze), and you can buy it in quite large bottles.

If you don’t need much dimension, you could try using clear verithane (from Home Depot, a hardware store, or maybe WalMart). It is a clear acrylic, too.

For real cheapness and easy access, you might try an acrylic floor cleaner, Future. You can find it in any grocery store with the floor waxes, but it is not a wax; it is a plastic.

Future gets very hard. It may yellow some, over years, but that may not be a problem, depending on your project. After all, if you don’t like it, you can always use it on the kitchen floor.

You would have to compare prices, ounce for ounce, but I think anything that you can buy locally in large sizes and then pour into smaller applicator bottles will save money.

Thanks for commenting. Please come back and leave another comment to let us know how it works out.

I tried Polyurethane but it’s too thin. Are you familiar with these dimensional adhesives? (They make things look like epoxy stickers. I see you say something about Gum Arabic being a dimensional Glaze.
