Hi guys. This is a reportback so you know what happened.
The tank from my 1951 G2 was badly encrusted with rust and gooey orange stuff, probably from the lead-replacement petrol that had gone off over the past 10 years since it last ran (here in South Africa).
Advice from a few of you herein was to give it long soaks in a molasses solution - so, being happy to take advice from experts, I tried it.
I brim-filled the tank with 1.5kg Blackstrap Molasses mixed with 14.5l warm water. I left it for 4 weeks, topping up occasionally. After 4 weeks, I emptied the tank to find MANY loose rust flakes and much clean metal. But not all the rust was gone, so I refilled the tank with a fresh molasses mix and left it for 7 weeks, topping up as necessary. When I removed the molasses with much shaking again and water flushing there was, wait for it, NO RUST VISIBLE.
But since I couldn’t see the bottom of the tank, I tried another method to get at whatever might remain. I was advised to use 1.5litre Dioxidene mixed in 1 litre water because it converts rust into iron, but it doesn’t remove the rust – so any flakey stuff remains.
After the treatment, and much shaking, lots of froth was seen but no other evident change and no increase in ust particles or other material.
So thanks to the few guys who advised, I now have a clean tank. Should I treat the inside with some proven non-peal stuff or leave it bare??
