Avanti Undercoating?

[Dunkin]

Were Avanti's undercoated, or just painted underneath?  Thanks

Both of my early 1963 Avantis (#'s 1122 and #1250) were bare fiberglass under the car.   I think most were like this

[Dunkin]

What about frame and hog troughs? Thanks

[lschuc]

Both would have been painted black.

So, if I look at a car with undercoating, especially on the hog troughs I should be suspicious? Thanks

All my Stude Avantis have undercoating. The 63 I am currently working on had primer before the undercoating. I believe the factory undercoating to protect the fiberglass from gravel and other debris being kicked up from the wheels. 

 

Of course, after all these years, the undercoating could have been added after the fact.

Often the selling dealer applied the undercoating as an extra cost way for the dealer to earn more.

Thanks yes, I remember there was factory and the dealer. I remember a company called Ziebart that did under coating. Thanks

Undercoating was an option for noise silencing (as much as you can silence an Avanti) rather than rustproofing.  As already said...it was a profit maker for the dealer.  Rarely if ever was it applied at the factory.

According to trivia question on this forum, "Undercoated Avanti" on 2/17/2019, the fender wells were undercoated at the factory. Additionally, most, if not all, photos in the authenticity manual show undercoating.

Ziebart did rustproofing.  Undercoat is primarily applied to deaden sound not prevent rust.

Well, if you read it in 'AVANTI TRIVIA', it HAS to be CORRECT!!
