Review: Best price per tube. - Black rtv is just a good all around silicone.I have been using black for years with good results where oil or water is involved.Ultra black and ultra gray are better for high pressure and red and copper are best for high heat. This is the same rtv that comes in some fel-pro gasket sets, just in a very small tube.
Review: Very good stuff! - Very solid drying silicone for most auto jobs.Works great on the china rails on Ford and Chevy small and big blocks.I have used it on oil pans and valve cover gaskets and have never had a issue. I buy it buy the case because the parts stores are much to high, I keep it in the house so it will last much longer due to temp being controlled.

**Q: Can you reseal a fish tank with this?**
A: I cannot see why not -- it is excellent for everything. But first, perhaps contact some experts of fish tanks -- retail stores, distributors, manufacturers, to be sure. The other consideration is whether or not the product may or may not contain chemicals harmful to fish.

**Q: I used this on accident for a rear differential gasket. I know it's the wrong stuff and I am going to remove it but has anyone else done this?**
A: keep checking it every week, if it doesn't leak why change itsupposed to use a gasket and nothing else but I have used this stuff inplace of gaskets in a pinch
