Rubber Body Fillers were used on late 60s Oldsmobiles & that term carried over & was improperly applied in the 70s.
That is probably why the person who might be in possession of the worlds most expensive 83 / 84 Hurst /Olds Air Dam
(refusal to submit requested pix raises uncertainties , not the fluctuating $3500 - $6000 price) believes them to be a rubber composite , as did I & all my attempts to repair them were misguided using that as my basis..
I plan to explain how thin flexible pieces with complicated forms like the side panels might suffer ill effects in a rectangular box , inadequetly supported for 30+ years & see if better images will be provided.
Co-operation to get images from specific perspectives that would determine the side dams maintained proper for , held tolerances & therefore fit every H/O with its original contours is much like repairing those panels while misguided by the common belief , due to incorrect terminology , the material was rubber.
Previous vulcanizing of rubber led me to understand the dam was not rubber...I endured that purgatory with multiple failed attempts.
Not being a huge fan of constant repeated failure , sights were set on an achievable goal & composition was left open yet always under investigation...
Characteristics of flexabilty & resilience of some percetage are in the oem pieces & very little in the 'glass dams.
Working air dams on stock cars earn their worth in very close contact with the track ,
A relatively smooth , flat surface with little deviation....
Roads & driveways are very much different.
Anything below the bumper will most certainly contact something attempting to occupy the same space & displace it.
Fiberglass yields only slightly before it breaks away.
Carbon fiber , a better , more expensive option ,
also has minimal flex before breaking.
My uncle was involved with the space program to the extent that many things he could not talk about at the time .
Anything associated with NASA had to have exceptional performance & be of the highest quality & that also is criteria for parts for my car
