Rusty petrol tank

[sth65pac]

Some GREAT ideas here.....

My answer.....was... Remove the sender, and ANY alloy parts! Fill your tank with 1/4 molasses, 3/4 water. Shake or premix!

Wait a three weeks (needs to be about 20C+ for molasses to work), Drain the tank. and the rust is gone.

Any holes you can braze up prior to putting in polyester if you fill the tank completely with water. DO NOT WELD... only braze, as you will get closer to heaven real fast! KABOOOOOOOOOOOM!

Dry tank completely (with hair dryer if you need to) and then fill with two pack polyester tank seal stuff (Motorbike shops know about it as it is used on steel tanks there), and problem is solved for about 25 years+

I like Richard's idea.... its less labour intensive & I might buy a mixer!!!
