[T3] Gas tank cleaning

[Maximilian Bukszpan]

Hallo,this is exactly what I am interested in too!!My 66 Fastback had a plugged gas outlet, so I had to take out the tank and we found a lot of gum and rust inside the tank!!My mechanic said, the old style to clean the tank inside was to take a lot of round little stones and shake the stones inside the tank until all the rust is gone, then flush with, hmmmmm, I dont know with what to prevent rust again, and then coat after everything is clean with POR 15, several stages of coating / sealing!!!What would be the "Soluable Oil"????????????????????I never heard about it, what description do you need to tell in a shop what you want????Will it also work with that oil even your car is stored most of the time, at least ten month a year, will the gas tank not start to rust again if it is just the bare metal and your soluable oil??? No coating to protect?????
Thanks for infos
