Has anyone tried Sharkhide Metal Protectant? I saw it on Two Guys Garage and it looks like it would do a great job keeping things from rusting, like master cylinders and calipers. Does anyone have any real world experience with this stuff? At $60 a quart I'd like to see if any Buick people have had success first. 
It also comes in a can, but it shows as discontinued on the website. Seems like that would be a nice thing.
