Repair Corroded Aluminium water tank
I have a 60' Sea Ranger with a floor tank about 4 m long and 0.5 wide and 0.5 deep. It has surge baffles that divide it into about 6 compartments. It sprung a leak so I undid an inspection cap in the end compartment and it had a lot of white chalk lumps all over the bottom and sides of the tank with slight pitting underneath. Removing the tank would be very difficult.
Has anybody had a similar problem and if so any suggestions on how to resolve the problem?
