I make a homemade version of millionaires candy.I put 1/3 block of paraffin to a package of melted chocolate chips. You can not taste the paraffin it just makes the chocolate glossy, and goes on smoothe and dries firm.

Please don't do that. My Mom used to do that for decades when making buckeyes and since we've convinced her to stop, they are SO MUCH BETTER! Yes, we lick our fingers a bit more, but that seems like a bonus to me. Eating candy isn't about keeping your fingers clean. Once chilled, your chocolate should remain firm at room temperature unless your house is really hot.

Shortening added to the chocolate is what is done now in place of the paraffin used years ago.
