While several different rod builders have created limited-production vehicles, few handled every aspect of the construction in-house, mainly because they thought it best to team up with other craftsmen to create certain aspects of their cars. While this takes nothing away from the quality or beauty of the cars they created, it does say a good deal about SAR. By keeping every aspect of the construction process in-house, SAR has been able to maintain personally set tolerances and control the design theme at every juncture, yet still build each car as if it were the only one. And because each of the Double Dozens is offered simply as a “roller,” the final results of each still depend heavily on the imagination, talent and individuality of their owners. In the end, each of these cars will be special in its own right, and we’ll be showing them to you in the months and years to come.

A NEW FLAME

Boughn started looking for a new truck, and when he saw a shiny red ʼ99 Chevy Sportside Extended Cab pickup at his local dealership, he knew it was the one. He purchased the truck and drove it home, but as with any true hot rodder, this was only the start of his adventure. On the way home he already had the finished truck pictured in his mind, and he worked toward that goal.

Corvette Expo 2026 & Chevys in the Smokies Take Over Pigeon Forge

The Great Smoky Mountains are famous for the blue haze that gives the range its name—but during the 49th Annual Corvette Expo 2026 and Chevys in the Smokies, the mountains were a little smokier than usual. Some of that haze came from cammed-up V8s, hot rubber, and thousands of horsepower rolling into Pigeon Forge for one of the biggest Chevrolet performance events in the region.

COVER YOUR BOTTOM

A Simple Approach To a Difficult Task

There are many ways to finish the bottom of any car. Whether you are building new, from the ground up or even detailing a rebuild that is not the off-the-frame type, you have options. And regardless of the extent of the refurbishing, you could even leave the underside in some shade of primer as it is easy to touch up, and the fenderwells and underside often become marked with use.

Simple Bottom-Side Finishing Methods

Other methods of bottom-side finishing are simple approaches, like painting the surfaces rattle-can black or using store-bought, spray can undercoating. Some home builders like painting their undercarriages black while others paint theirs body color. There’s also a selection of undercoating treatments, or you can use any combination of these methods on particular areas. Most high-end, highly detailed cars that are built nowadays have fully sanded and primered under panels that are fully painted in the same color as the exterior, including the clear.

Challenges with Fully Painted Undersides

While this is the best-looking finish, it is the most time-consuming and expensive to do, and it is not the most practical due to damage from road chips and debris. Also, if you’ve ever had to clean one of these fully painted undersides or—even worse—had to touch up the undercarriage after a season of even minimal driving, even though you enjoy looking at these highly detailed cars on the show floor, you know this approach is not for you. If that’s the case, you may enjoy the product we are about to discuss.

The Show Car Buildoff ’55 Underside Coating

The Show Car Buildoff ’55, one of three cars being built by Woody’s Hot Rodz for an eventual shootout, was conceived with several thoughts in mind, not the least of which was the fact that these cars are being built to drive. Taking this into account, Woody’s thought it best to go a different route and coated the undersides of the three cars. Shown here is the ’55, which was the first of the trio to receive this unique bottom coating known as SEM Pro-Tex Tintable Truck Bed Liner.

Chassis Protection and Detailing

While the Art Morrison chassis was double-powdercoated to protect the chassis inside and out and to highlight this high-gloss finish, Woody’s incorporated Totally Stainless fasteners throughout, which are now available in kit form for the AME chassis. To go along with the polished stainless fasteners, stainless brake lines and aluminum brakes from Wilwood provide a great-looking contrast, and the chassis should not only stay rust-free but will also be durable and easy to clean.

Application of SEM Pro-Tex Tintable Truck Bed Liner

To finish the underside project, the SEM Pro-Tex Tintable Truck Bed Liner was purchased from a local parts store (Smyth Parts Plus) in Cincinnati, Ohio. This product is actually designed for truck beds, and because it is tintable (the bed liner is clear to start with), when tinted it will provide a custom look for the underside of this ’55. Another advantage is the fact that the liner material will add another noise barrier in addition to the Dynamat because of its absorptive properties.

Benefits and Installation of the Liner

The installation is simple and straightforward, so follow along as it is applied to the underside of the Show Car Buildoff ’55. This tri-5 will see lots of road miles this summer, but with SEM liner material applied, it will only need to be rinsed off, virtually eliminating any maintenance on the bottom-side finish.
