Quick Help: 3M film or not?

I should see if I have a warranty booklet in my glove box then. My film is still holding up well, but not much sun up here. Its working well for me so far since its preventing rock chips and scratches.

 

While this is a good idea and great product, it won't protect the paint from chips and scratches... But it will protect the paint from the road salts and other crap, they use,... What kind of price are they charging to coat your truck?

 

I was thinking of trying a Derp hood protector. We'll see if I get ambitious this spring.
