Just got my 2010 done for the third time. I get 'Rust Check' as opposed to 'Krown'. But same thing...applied same way. I have been doing my vehicles for past 20 years...I swear by it. And so do the people that by my used vehicles from me...........

I had the wife undercoated at Krown. Still going strong, no squeaks either.

The problem with Krown is that the mixture they use is to runny and drips away and gets washed away fast. I see no point doing it prior to winter and then again after.

I've seen the results of krown rust proofing, they aren't too impressive.

That's not the problem with krown, that's one of the reasons it's effective! It displaces moisture in small areas that thicker products can't get into. Yes it does drip, but that's how it works.
