when I cleaned the rust in my tank, I used a small rubber drain plug to fit tightly inside and just a little sticking over the filler hole, and i screwed a small piece of chain about 2' long to the bottom side of the drain plug. I filled the tank with muratic acid, and installed the drain plug with chain attached, then shook the everlasting stuff out of it, and let it sit for an hours with the acid still in it, then gave it another shake, roll, twist, and any other type of movement to get the chain everywhere it could possible go. and that worked great for me, after i rinsed it out several times with water, and then a final wash of acetone, i coated the tank with red-coat brand sealer.
