Undercoating worth it being in the midwest? Salt Hell

[JETZ]

What the bodies are dipped in is called 'E coat'.

LMAO.. I had to stare at that for a moment to figure out what the hell you were talking about.

Back in in 85 I bought new 300ZX. I wanted my new toy protected so I went to......Ziebart.
Took it in yearly for the annual inspection, and touch up (think it was $99 then). I really took care of that car. To make a long story short, I started to get blistering in the rocker panels. I took it in to the same shop, but denied my claim. Ended up that I had to get a lawyer to threaten a lawsuit before they paid to fix the car to my satisfaction. Their product at the time was a 'wax type', and ended hardening and 'cracking'. Where the cracks opened up, the rust started. Both rockers had to be replaced. I was not a happy camper.

So that's a NO, not like Krown at all. To be honest I thought they were out of business. Never heard about them in advertizing on radio/TV, newspaper, magazines...and never wanted to hear about them. No one I know, ever mentioned them, its all Krown, or Rust Check (same type of product).

Your right the ancient tar spray was what I was referring too.

Krown looks similar to that the old Ziebart Rustproofing system?

Krown+Rust Check are nothing like the old Ziebart you're thinking of . They will run into all the interior seams and coat everything well. Underneath I like to think it's good for all the rubber pats as well. It can be argued that exposed areas will get washed away a bit in heavy rain,but it gets done yearly so I don't worry about it .

We live near the beach in a high humidity environment, and its an absolute must to have undercoating applied. If it is not done, you normally face a lot of rust damage after a few years. It is evident to me that typical anti rust treatment of the under-body (if done at all...) during the manufacturing process is not at all sufficient.

After a few years the treated areas show a major difference with untreated cars, and it has become a car life extender.

I think it is worth the investment if living in corrosive areas.

I use Rust Check here in the Great White North. Best to get it done while it's warm out as I beat the crowds of customers, keeps my Rust Check guy's food on the table, and gives the product time to creep through to all the seams better.

Although I've never heard of it, it seems Corrosion Free won out in this article. Back in '79 I used Ming rust proofing on my 1979 Olds 98 Regency. Haven't used rust proofing since then on any vehicles.
