Hot Rod Flatz Black Paint Job Completes Show Car Project

Recently we officially ended the Hardcore Knight project without ever really addressing the paint job. Since it is the first thing you notice on this car, it bears some attention.

The flat black from Kustom Shop’s Hot Rod Flatz collection was used to finish off this project. What’s great about this collection of paints is that it has that old school rat rod feel, but with a durable paint system. This whole flat paint look came from the days when guys would hot rod their rides, but never got past the primer stage when it came to paint. It may have been due to lack of funds, but more likely, since it was in the early days of hot rodding, speed was king and fancy paint jobs came second to horsepower.

The evolution of dimensioning

Written by Timothy W. Morgan

Repairing a damaged frame on today's vehicle designs requires more accurate dimensioning and newer repair techniques than ever before. The "old oak tree repairs" have been gone for years. With the birth of the unibody came three-dimensional measuring systems and fixtures, which replaced tape measures, tram gauges and centerline gauges. Now as we fine-tune our facilities to improve our efficiency and work quality, we move into the age of computerized dimensioning.

Mentoring and reduced cycle time go hand in hand with success

Written by Toby Chess

Recently, an insurance carrier asked me to make suggestions as to how they might improve cycle time at some of their repair partner shops. My belief is that the cardinal rule for improving cycle time is that complete estimates need to be written up front, and not loaded with supplements on the back end. In other words, the vehicle needs to be torn down at the start of the process and a very detailed estimate written.

Safe use of ultraviolet-cured primer-surfacers

Written by Autobody News staff

A few years ago, ultraviolet (UV) cure primer-surfacers were introduced to the collision industry. These products use UV light to initiate cross-linking of molecules in specially formulated primer-surfacers. The coatings fully cure in about two minutes. An Advantage Online article "UV-Cured Primer-Surfacers" was published in March of 2002 about using these products.

Troubleshooting parking assist systems

Written by I-CAR Advantage Online

Rear and side view mirrors at one time were the only assistance that a vehicle offered a driver trying to back into a parking space. Today, several vehicle models are equipped with a type of parking assist system that not only helps when parking, but when backing up for any reason. Some parking assist systems also help drivers when moving forward. Parking assist systems are often standard on station wagons and SUVs and are usually optional on sedans.

Head-Up Display units making comeback

Written by I-CAR Advantage Online

What's a HUD? Head-Up Display (HUD) units project information from the instrument panel to the front of the windshield so the driver can maintain focus on the road. The projected image usually appears to hover over the hood of the vehicle, a distance close to where the driver is already focused. This might be why this accessory is offered not only as a "high-tech" gadget, but also a safety feature.

I-CAR welding test challenges even experienced techs

Written by Toby Chess

Last year, I was hired by Holmes Body Shop, a large Los Angeles-area chain, to set up training and quality control procedures for the company. About a week into the job, I inspected a vehicle that had new front end structural parts installed with plug welds. Though I couldn't determine their exact structural integrity, the plug welds visibly ranged from good to poor. While the technician prepared to redo the welds at my suggestion, I observed his welding techniques while performing some practice plug welds.

Foam now used to increase crash protection

Written by I-CAR Advantage Online

One hundred years ago, vehicles were built without consideration for noise, vibration, and harshness (NVH) control, or occupant protection. These vehicles were designed for function alone, which was primarily to transport people and goods from one place to another. As vehicles evolved through the years, they were built with more attention to creature comforts and accommodated the passengers by increasing occupant crash protection and reducing NVH.
