If I have an extremely old vehicle that has limited parts availability for replacement, how would I fix a rusted gas tank in order to put it back in service in a vehicle?
I've run into this issue a couple of times in my life and would like to hear procedures and effective methods to remediate this problem.
I have fixed many motorcycle gas tanks that are rusted, but never on a car.
Is a coating recommended for the inside of the tank?
How would I get all of the rust out of it?
I've used electrolysis with sodium carbonate to remove rust from smaller parts in a 65 gallon plastic container but the size of car gas tanks obviously makes this prohibitive. Here's the basic procedure I've used in the past for just parts.
