Hey Scotty for someone living in Michigan who plans to buy a new car in the near future. What’s your opinion on krown rust proofing? Does it actually work. Is it worth the $130 /year . I’ve heard good things about it
Krown is one of the better undercoating formulas out there. I personally use Rust Check but Rust Check and Krown are very similar formulas. Fluid Film is another good formula. I would definitely pay $130.00 to have it done and I would do it every year. Here in Nova Scotia Canada I am living right in the rust belt and I can see first hand the difference that it makes. Whatever you choose you want something oil based, not far or waxed based because that stuff can actually crack and then trap moisture against the metal as shown on the South Main Auto Repair. But you can't go wrong with Krown.
no such thing as rust PROOF. At best, it's rust REDUCE.
I don't think I would pay $130/yr
Best you can do is mitigate. Scroll to 4:10 (you can try it, but no guarantees):
