Has anyone used "Opticon" on their stones for cracks and what I call "divots"? I have some stones that have small cracks and holes that I have been using Epoxy 330 on to fill. I tried to find Opticon on the web for some information but could find nothing for our use. Has anyone used it, or is anyone familiar with the stuff. Can anyone tell me if it is a two part system like epoxy or is it a one shot thing like "superglue"? If you have used it, does it polish up like the rest of the stone? I'd love to hear any pro's and con's, if you've used the stuff. I haven't tried superglue yet and maybe you folks can tell me if that (superglue) is the best for filling in cracks and will polish like the stone. Ancious to hear from you.

I agree with hummingbirdstones. I tried it many years ago on cab material and it did not work well for me. I now use a different dop method and I end with a soak in acetone so it would not work for me now. Have not used it to "seal" stones for tumbling. |

I used some recently on some BC Ocean stone cabs for my BIL in belt buckles. The brown part tends to be a little porous so we used it on the mostly finished cabs and then resanded and repolished them from 600 grit. Since it was our first use I treated more samples with mixed results. it worked with porous but solid stuff pretty well, but fractures and any pits or voids that aren't really small don't seem to improve much. I cleaned in acetone, dried and warmed to about 150 degrees F, then brushed on a thin coat of the resin, then put back in the oven for a few hours. Don't do this in your kitchen oven, the fumes are nasty. When I pulled them out I put another thin coat on everything that had soaked it up, and then back into the oven for a short time. When it came out I prepared a little resin and hardener solution according to directions, and brushed it everywhere with a disposable acid brush, then back in the oven for a couple hours.
After that it took about a day to cure nice and hard. Next test will probably be the art resin.

Rockoonz - Thanks for that information. It sounds like a lot of work for little improvement. Correct me if I'm wrong. I'm thinking epoxy resin, like Art Resin or 330 resin is the better choice for what we are doing. Thanks again for your information.
