Not quite. The owner of KBS used to work for POR as their chief chemist and developed a lot of their products. He went out on his own in Australia and refined the products and formulas as POR had no inclination to make their products better. KBS is getting a good name in the US as well.

I have had diesel sitting in this old tank for a few years with no leaks.
Now ready to use it so I pressure cleaned the inside as it had a fair bit of rust in it.
Painted the outside and thought to put a few litres of diesel in it before installing to be sure.
No, its weeping to my dismay.
Found this thread and was wondering if there are any new thoughts or updates on sealers.
