many here will recommend RedKote.... It's what I used, it's only been in the tank for about 4 months now, so no word yet on how well it worked for me. I decided to use it because every radiator shop in town that does gas tank work uses it, and all say that they had good luck with it.
What ever you decide to use...FOLLOW THE DIRECTIONS TO THE LETTER!!!! and make sure that tank is BONE dry before you dump in the liner.
PM me if you have any specific questions.
