Question 1

would this make my paper crafts stiff, if I used it on coat them?

Accepted Answer

I had never used this on paper before.  I have used it to repair the surface of castings.  In response to your question I took a piece of origami and sprayed it.  The spray did not do any damage to the paper.  The paper was left with a mild sheen.  One coat did not make it stiff.  Maybe more coats would make it stiffer. It did look like the paper had a protective coating.

Question 2

Will this harden and protect a sand dollar -- basically keep the sand dollar from cracking and breaking?

Accepted Answer

No, this isn't what you're looking for. This is a sealant for resin, not other products. However, you might consider either 1: brushing or dipping the sand dollar in resin, or 2: Triple Thick Sealer. I think resin will probably work best for you--check out the website Resin Obsession for more info. (Not affiliated, just love 'em.)

Question 3

can it be used to coat baked polymer clay coasters and can it be used indoors?.  How strong are the fumes?

Accepted Answer

It can be used to coat baked polymer clay pieces, but you could end up getting a "cloudy" look if there's any humidity in the air. This thing has pretty strong fumes and I definitely wouldn't recommend it indoors. The bottle says to use in a well-ventilated area, and I'm assuming that means "under a venting hood" if you're planning on doing it indoors.

Question 4

What is this product mainly used for and do I need to buy it?

Accepted Answer

No you don't "need" to buy it. It's used to seal off resin pieces to protect them from finger prints, fill in minor flaws and such. It's handy but not mandatory.
