Cost to Sandblast a K-member

You guys do know that acid will take rust off asap? Yes it is not the best thing to fool with but a plastic container filled with PPG DX579 and water will bubble and take the rust off smaller items like bolts and smaller hardwear.
You can also take Muratic acid{used to clean concreate and bricks} and clean body panels but it must be nutralised after. It is nasty stuf so i would not use it due to disposal problems
