I picked up a blazer gas tank from a swap meet yesterday ( guy threw it in with power windows and pdl for my chevelle for $50) and the tank has some rust inside I was going to use the por-15 kit but before I order it I would like to know how much rust is too much rust inside the tank, looks like surface rust but there is a bit of it

thnx in advance

This can be tricky. Blazer gas tanks are infamous for rusting out. If you can find one that is original it is usually expensive. So if there is a lot of rust I am sure it leaks or is about to leak. If it can be repaired, you should be able to get a pretty penny for it. I think the only way to find out is to clean it and use the kit and see if it holds.

TOO MUCH RUST: thats when you put the gas in thru the top and it comes out of several holes in the bottom

The POR-15 will take care of pinholes with no problem. Best way to clean out the rust is to put something in the tank and rattle it around. I've used small chains, steel nuts, even 1/2" screen granite. If you have some small rock with sharp edges, it will work. Pour in a handful, slosh it around, then clean out the tank with water. You can then inspect, and see if the tank leaks. No leaks, then order the sealer. Just remember to follow the instructions to the letter.
