that's pure nonsense. it's very cheap and will preserve your car very well.
krown, rustcheck, corrosionfree, carwell, fluid film
I am with wolf359,
FXjohn, pls quote your source for claiming the above is nonsense.
just think about it, drilling hole into your underbody will protect it better?
wow, the best thing you can do for you car is wash it, and wash the underbody with a hose.
if you don't drill and undercoat the hollow sections they will simply perforate, in other words rust from the inside out. if you only keep your cars a few years, this isn't for you, stay ignorant. look underneath a car that has driven in salt a few years. and look at all the rust starting on door edges, wheel arches, cab corners, windshield frames, etc, etc.
