Gas tank sealing

[Cutlassjim]

Anyone have any experience with this? After looking around both the Eastwood and POR-15 kits have a lot of bad reviews. I was looking at this kit

And if you have done it any tips on application so I don't FUBAR my tank?

I've always used liquid metal for leaks. That kit looks way better, lol.

I don't have any leaks it's just starting to develop some surface rust on the inside and outside of the tank. I had it done on my motorcycle tank years ago but I have no idea what they used.
