As the subject says - can you do it and what would you use?

It's better to use a deep cleaning product and then seal the tank with a kit such as one from Frost. There's an internal filter in the tank - it's best to remove this first otherwise you'll be stuck with a sealed filter...

+1.

 

I would think anything you'd spray in the tank would wash off with the fuel.

 

POR15 also have a great tank sealing kit.

The filter that is about 2" away from the walls of the tank?  if you manage to get paint on that, you're doing it wrong
 

I used the Por kit (3 stage) from Frost.  Worked a treat.  All details in my build thread.

It's in the middle of a baffle plate in a van tank and thus easy to cover (see my build thread for my monumental balls up!). Not sure on the saloon ones though, but as you have to rotate the tank anyway to cover the inside I would be careful as it can get EVERYWHERE!

If you are only dealing with surface rust, clean the tank and keep it full of gas to prevent corrosion in the future.  Save the lining/coating kits for fixing leaks and saving RH (or very early) tanks.

 

Interesting timing of your question.  See the thread linked below currently running on MM.

I've now welded the neck of my tank so the question is more about how to treat the weld on the inside of the tank to help stop it rusting. I would imagine just a lining of POR around the inside of the neck should be fine. It's not like it will be in permanent contact with petrol so should last ok I reckon.

Obviously this is your choice and your tank, however, I don't anticipate that you need to do anything special to protect the weld.  I know that in some instances welded areas do tend to rust preferentially compared to surrounding metal but this will be inside a gas tank with limited exposure to water vapor.  It is extremely unlikely to rust through or cause you other problems if left uncoated.
