I was planning on posting pics yesterday (or the day before... can't remember) of this project. However, the "epoxy" on the foam part took a bit longer than expected. This is because the fiberglass resin we used did not cure nearly as fast on the rocks and foam as it did on the brush. I'm not really sure why that happened, but it seems that wherever we applied it relatively thin, it did not cure quickly. So, we did a second coat and put it on the foam thicker. This seemed to help and it looks pretty good right now. Being relatively careless as far as where we applied the sand helped it stick to the rocks in a few places and helps it look natural. Also, it is relatively difficult to get the sand/crushed coral to stick to the fiberglass resin "against gravity." So, we have another coat to apply to get the places that were upside down the way we had the rocks sitting before. We'll take these as lessons for next time. I think it looks really good though and, especially if you did an entire tank this way, you'd never think it was anything other than a rock wall. Pics to follow as soon as we finish (hopefully tomorrow).
