Title: Ziebart Undercoating
Post by: Smity on March 16, 2021, 02:45:19 PM
Is anyone familiar with Ziebart undercoating?  Have a 68:that had this applied when the car was new, not sure if this negatively effects the value of the car..

I remember when it was offered (and maybe it is still around?) - but never had it applied.

That is because I was told that the service requited that small holes be cut to access some areas with the spray wands.

Not sure if that is 100% accurate or not.

There are so many items that go into determining the value of a car, that one factor alone might not make a significant impact.

It depends on history and many other items

It does make it much harder to evaluate the condition of the metal. Ziebart also drilled and plugged holes on many occasions

Overall it certainly is not going to enhance the value.

I personally would say its a negative

Had it done to my KR, while it may have made the underside looked bad and they did put many holes in various places, I haven't had to do all the rust repair that has been necessary on my '67. If I lived in Arizona, I could have avoided both.

+1 with Coralsnake.
I have seen the yellow plugs all over the place when I open the doors. They would be on the rockers and door jambs. Then I see undercoating all over the engine compartment. This would be time consuming and expensive to repair.
So I would say it is a deduction to the value of the car.How much? We can all have our own # on that.

Some Ford dealers offered same service and required the same 1/2" holes but had "official" Ford plugs. I think that if I had a car with a bunch of yellow plugs I would replace them with the Ford blue ones.....if you can find them

When you're a kid with a car, what do you know?

In the '70s and early '80s, corrosion was a big issue with domestic cars and rust proofing was popular. I had two cars in NY that were rust proofed and 40 years later, they are corrosion free. Quality depended on operator skill. Ziebart was a big retailer along with Rusty Jones and Tuff Kote Dinal.

As for a rust proofed Shelby upsides would be the owner drove the car and protected it so it's still solid today. To me that's a win win.

I agree! I'd rather be fixing a few 1/2" holes than floors, quarters and rockers. I bought my 68 KR in 1981 and had the doors Ziebart coated in 1982. I removed the door panels and never had them drill any holes. Had no thoughts back then about the cars value / originality etc. Just wanted to keep my rust-belt car from going back to nature.

68 country sedan and Don,
I see both of your points and understand that can be a +. The red KR that sold at auction in Indiana had been ziebart. Yellow plugs and undercoating everywhere. It sold for an unbelievable amount. Something around $250k .Huge money. But since I am a body and paint man , I do not want to see those plugs when I open the door. And the 4 places that rust in the engine compt. On the 67-68s were still rusted.Nothing wrong with different opinions.

10-4! When I bought my car it was to be a driver, so I never thought about resale value or selling. I still have it! Was lucky to get a Scottsdale, AZ car.

Very good points made regarding current condition with and without rust proofing.  Here in northern New England, a new, daily driven, period car would be so heavily rotted after only three years it may not pass the annual safety inspection.  Keep in mind, many internal areas were bare steel.  Ziebart was a franchise some dealers offered.  Was hugely profitable.  However, quality was entirely up to the kid entrusted to do the work.  Believe there were a number of warranty suits that damaged Ziebart.  Not sure if they even exist anymore.  Locally, Fluid Film and NHO (New Hampshire Oil) are annual efforts.  Both work OK.  On my new purchase opted for WaxOyl applied by the most experienced and respected applicator in North America.  Maybe 60 years from now the car will be discussed on a forum debating my decision.

  Well, I can tell you that it worked.  I must have had the last non-rusted 77 Volare wagon in the south Chicago suburbs.  But, I at least had the car Zeibarted within one week of driving it home frome the dealer.
  I do  recall looking at a 67 GT350 (not mine) that had been Zeibarted but that was done about 6-7 years after being sold new.  That is too late to have stoppd the start of any corrosion.

Results were dependent on the shop who applied it. Tuff Kote used to do used cars. I thought Ziebart only provided warranties for new cars (5 years?)

My 1st new car was a 72 Mustang sportsroof with a 351 C.  The dealer at the time offered undercoating with a lifetime warranty for the original owner.  The metal used in those cars at that time was so bad I went for it. I only drove the car in the winter the 1st year and stored it other winters and still had at least three or four free repairs - mostly to the tail panel around the rear lights and the back of the wheel house area and trunk drops. I recall the metal was almost paper thin in some of those areas.  I kept the car for 7 years and it still looked like new when I sold it, so I was very happy I went for the rustproofing.

If I remember correctly, Ziebart had a similar warranty, but you had to have the car redone every so often. (yearly?) I think you had to pay for that so almost no one kept it up.

Back in 1978 I bought a new K5 Blazer and had it Ziebarted immediately because Blazers were notorious rust buckets. After about 6 years, the only rust was on the bumpers, even though they were coated on the backsides, and the metal part of the roof(!). It seems Chevy painted that with a new material that wasn't supposed to require primer. Hah! GM did cover the repainting, but I've never looked at buying another GM product since.
