There's nothing wrong with cleaning and coating your tank. If you have the money laying around to buy a new one go ahead. The "kits" you can buy to clean and coat your tank use Phosphoric acid, the same stuff that's in Coke. It's slow and expensive but fairly safe to use. Muratic acid is very fast and cheap but dangerous to use. You can get it anywhere pool supplies are sold, hardware stores too. If you use Muratic acid it's wise to kill the acid by pouring in several gallons of soda water before you dump the acid. I've used several kinds of coatings and prefer
Red Kote I get mine locally at the Bumper To Bumper parts jobber. I've said before and will say again those who have trouble with tank liners are those that don't follow the manufacturer's instructions.
