That looks like the thing to buy, and I'll use that the next time I need to derust a block.

I've used Rust911 for 5 yrs. with superb results. It is an excellent product.I just do not understand why people play around with acids when this superior product is available. Works really well to derust the inside of the gas tank. It comes out spotless.
