I bought this before for $32, now its $37, why a price hike of 15% in under a year?

Its 2022, Supply Chain Issues, shipping delays, pandemic restrictions? Surprised it's not $45.

Can you reseal a fish tank with this?

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.

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?

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
