I've got fire and ice, but I did not install myself. I did do the sealing.

I did not enhance, but it's up to you. I tried regular sealer, enhancing sealer and no sealer on my sample and then stain tested each of the 3. I happened to have both types of sealer at home, so it didn't cost me anything to try them both. Here is a picture of my sample, although the picture is not great, but you can see how the enhancer changed my sample. You might be able to see how the enhancer made some green come out in some of the pieces, and I didn't want green so I didn't enhance. I also replaced some of the white and peachy glass tiles with the darker amber tiles which are also in the picture.

I posted the results of my stain testing on a thread which I have linked below. Scroll down about 3/4 of the way. It tells the kind of sealer I used. I have been very happy with my sealer - no issues with staining, everything wipes right off. However, it did seem to lighten the fire and ice a little bit, or maybe leave a little white haze on it. The directions for the sealer say to apply it, let it sit for a while, then wipe off the excess. I think I didn't get the excess wiped off well enough, and this caused the slight haze. IIRC, I put on 2 coats. I sealed last August and have not sealed again. I don't think it will need it again until at least August, and probably not then.

My installer left the tile on the mesh backing. It is definitely meant to be installed that way and it would be a much bigger job if you took it off. I would recommend that you remove the mesh behind the glass pieces, however. My installer did not do that, and the mesh shows through some of the glass pieces, even though he used white thinset as specified in the installation directions.

Good luck! I love my fire and ice and I get lots of complements on it.
