how many cans of this would it take to do the under-body of an average sized car?

This will accelerate corrosion by trapping moisture and salt as it degrades. You want lanolin based coatings that can remove moisture.

Not sure how exactly a hydrophobic coating can remove moisture. The idea is that because it's sticky that it won't crack off and leave a gap like a rubber coating. Really it's all about the prep work.

Wondering if I can use this on the bottom side of a kayak to protect it. Kinda like a truck bed liner?

For those who care this is Asphalt-based not a pure rubberized compound like truck bed liner. Certain applications prefer one or the other.

Is this similar to plastidip? Can it be used to black out car parts or chrome etc. ?

Has sound deadening properties if you would like to try and quiet the ride.
