I've got The Beast
on the ropes. The tank sat soaking in my home-made Dip all weekend. Now I can see more metal than scum looking in. I plan to finish him off with the suggestions I've received. Thanks for your kindness. Cycle 3 began last night with another batch of Dip. I keep changing the recipe according to how much I've got left of each ingredient. I threw a bunch of metal - worn-out screwdriver bits, nuts, bolts, Allen keys and wrenches - in last night and agitated a while. One final Car Wash trip under cover of darkness and it'll be time to apply my Yamaha-branded tenk treatment. Should be ready for fuel after that.
