Conservation and restoration of road vehicles

Vehicles, whether partially scrapped or completely totaled, are typically restored to maintain their roadworthiness or to preserve those with antique status for use as showpieces.

Bus preservation groups aim to purchase buses of various eras to restore them to their original operating condition.

There are help sources, books, and magazines (Skinned Knuckles in the US or Practical Classics in the UK, for example) to assist with restoration of an entire car or specific parts.

This highest level of Restoration is distinguished from "Traditional Restoration" because a Concours Ready Car far exceeds the quality of the original manufacturer in its original debut day, because, the high standards set by judges at Concours D'Elegance events worldwide, demand that not a scratch or nick be found on even a single nut or bolt in the car being exhibited, as one example.

The ultimate goal was to put forth the maximum effort toward uncovering, referencing, documenting, and preserving any and all existing components and finishes.

[8] The process of restoring some particularly rare antique vehicles back to their overall original showroom floor condition has become increasingly difficult over time due to the diminishing of resources, parts, and tools.

"[1] Upgrades that are easily reversible to the original stock condition, or changes that were available options when the vehicle was first sold, are less likely to be controversial.

Less acceptable to the classic car market may be major alterations like engine swaps or gearbox transplants, which would be more like hot rodding.

Emissions upgrades include hardened valve seats to use standard unleaded fuel, or retrofitted catalytic converters.

While it turns out a set of lifters would've cured the problem, in the best hot rodder tradition, Young saw it as an opportunity to tear down the motor and build something better.

The goal was a reliable, street-friendly, pump-gas engine that was capable of easy 12s on street tires, all the while retaining a factory restored appearance—including iron intake and exhaust manifolds.

[10] According to Young, many enthusiasts were displeased with the changes and felt that his modifications compromised the originality of the extremely rare car, being one of three built like it.

"[1] Replica restorations are often performed by enthusiasts who want to imitate specific rare or famous vehicles, such as one from a particular movie or TV show.

"[11] Trey is quoted in the article saying "I really wanted a classic GTO, but with the power, ride, and comfort to rival modern cars—a great car to drive.

At the same time, I didn't want to heavily modify an original GTO or Judge and put lots of miles on it, because I would feel guilty for depreciating a piece of history, so I decided that a tribute car built as a resto-mod would be my best choice.

"[11] Some individuals within the auto enthusiast community disapprove of replica restorations due to the prior cases in which some individuals performing said restorations, such as turning a 1967 Pontiac LeMans into a replication of a Pontiac GTO of the same year, a rarer model, and fraudulently selling it advertised as the rarer and more sought after model with the higher price tag.

Henderson bought his 1928 Ford with 80 years of body and paint wear but decided only to bring the vehicle back to running condition and left the exterior as it was.

Some businesses focus their work on only specific components, such as engines, gas tanks, clocks, or chromed parts.

For example, even if a wheel is covered by a full hubcap and not seen, and is structurally sound, it should have the tire unmounted and any required repairs performed such as rust removal, straightening, priming, and painting.

Wooden parts should go through the same meticulous inspection and repair process with regluing, replacement of rotted or termite-damaged wood, sealing and refinishing to match the factory specifications.

Fasteners with tool marks, damaged threads, or corrosion need re-plating or replacement-unless the car was originally sold that way.

Often abrasive blasting of the frame is the most expeditious method of cleaning, but it may still leave microscopic rust pitting behind, so should be followed up with a phosphoric acid 'rust killer' solution, before priming.

Acid tank dipping of the frame and or body followed by an E-coat primer after repairs is recognized as the most effective but also most expensive way to get rid of rust and to protect against future corrosion.

The instrument panel or dashboard contains a number of gauges, each of which has to be inspected and cleaned, repaired, or replaced to be brought back to both operational and cosmetic standards of the car when it was first sold.

Examples of this include leather seat, dash, console, steering wheel, door panel, and trim repair, as well as re-dyeing.

[19] In which case a replacement part like a fender, front grill or door mirror must be purchased outright from an external source.

At one time it was common practice to use lead loading to achieve tight panel gaps, especially in the coachbuilding business, but also on the production line.

It is highly advisable to hire experts such as Torqued Custom Auto Detailing & Ceramic Coatings in Riverview FL to perform this task.

[21] Typical parts that require replacing include the pistons, spark plugs, fuel lines, battery, fuses, timing belt and various gaskets.

A mechanic can provide specific instructions on which chemicals to use on older paints and metals in order to preserve the integrity of the frame.
