Aftermarket Automotive Woodgrain Vinyl Products:  The Full Scoop

Aftermarket Automotive Woodgrain Vinyl Products: The Full Scoop

The woodie has been part of the auto industry since the very beginning.  Originally, portions of the vehicles were made of real wood.  Later, auto manufacturers began building all steel bodies and creating a simulated wood effect using printed vinyl sheeting adhered to the metal base.

Throughout the history of aftermarket woodgrain material, 3M has undoubtedly been the leader in development and production of high quality simulated wood film.  For many decades, Di-Noc was the gold standard of automobile woodgrain vinyl.  

I personally began my career as an auto graphics installer in the mid 80s and became very familiar with the 3M Di-Noc line of products.  Throughout the next several years, 3M began to reduce its offerings in the woodgrain film market.  This was also likely fueled by design trends of the auto industry as well.

In the late 90s the colors available were down to 3.  These were the most popular and widely used woodgrain films in the auto industry.  As we came to know them, they were Marine Teak, Cherry Oak, and Burma Teak.  Marine Teak woodgrain film was used exclusively(to my knowledge) by Jeep on the Grand Wagoneer from 1987-1991.  Prior models had the Cherry Oak Woodgrain material applied, but the Cherry Oak was not used only on the Grand Wagoneer, it was widely used by Chrysler on many vehicles including the Lebaron, the minivan and the PT Cruiser.

Once these vehicles equipped with woodgrain film were discontinued, film production stopped as well and enthusiasts and restorers were left to scramble for any remaining new old stock hiding in the dark corners of dealership parts departments.  Eventually, the supply was depleted and we had to come up with an aftermarket product to assist in the maintenance and restoration of these vehicles.

We took notice of the dwindling resources and began acquiring whatever original films we could get in order to provide a close replacement product.  The trouble here is that the original woodgrain film was printed with various brown inks onto different brown base films.  Reproduction woodgrain material is printed with high end, large format digital printers and overlaminated with a clear layer to protect the color. 

This all sounds good if you can match the original color.  Well, we could get into the science of color and light but that is a blog in itself (a very long one). But to be brief, digital reproductions are printed with at least a 4 color process, usually black, yellow, cyan(blue) and magenta.  To achieve a brown hue, various amounts of each ink are used to create the closest possible match.  Unfortunately, the match is literally in the eye (and light source) of the beholder.  A perfect match in noonday sun will not be perfect in the early evening.  There are different color shifts based on artificial light sources as these will be warm white, cool white, daylight or full spectrum bulbs.

With that being said, it is not recommended to use a reproduction woodgrain panel as a single repair.  This will NOT be a perfect match in all lighting, EVER.  If a repair is necessary, a full side must be done in order to have a smooth color flow.
