“Technology that restores the 2nd-gen GT-R’s degraded body!” Can we implement electrodeposition coating regeneration methods to save as many GT-Rs as possible?

Garage Yoshida restoration technology completely regenerates the body of an eroded GT-R
This electrodeposition coating is also implemented on new car production lines!
With even the final BNR34 Skyline already reaching an age of 20 years old, we look here at an 2nd-gen GT-R. Performing regular maintenance and care on the vehicle may not even be enough, as age takes its toll and the body gradually deteriorates.
In addition, even with a pristine appearance on the exterior, there are cases where rust and deterioration have already taken hold, especially along the bottom and lower sides of the body. Vehicles driven in snow prone areas and coastal regions are especially subject to salt damage. However, vehicles stored indoors may also have damage that has progressed over time, whether we notice it or not.
Garage Yoshida has specialists working on GT-R regeneration in response to the owner’s desire to continue riding their beloved car for a long time. This method can allow full restoration from the engine to the undercarriage to the body all in one go. However, the method which is attracting particular attention is electrodeposition coating of the entire body for an ultimate regeneration not found elsewhere.
Mr. Yoshida tell us, “We have seen newer vehicle production taking stronger anti-rust measures, but still over time corrosion can spread and become a serious problem. What might appear as mere surface rust could in fact have full corrosion throughout the steel plate. In this case, we are often faced with the only option to replace the panel.”
Before we fight corrosion, first we need to determine the extent and make necessary preparations for restoration. Rust removal uses a wet blasting method, but when the damage is too severe, the structure cannot be retained. In such a case, fine surface rust is removed by wet blasting while performing patch processing of the structural areas with a steel plate.
As you might guess, production on many parts such as frames and body panels have been discontinued. Therefore, according to the degree of damage, Garage Yoshida sometimes responds by preparing a donor vehicle for a transplant, or manufacturing necessary parts specially from an iron plate.
A notorious weak point on the GT-R is the strut tower panel, which replacement parts were no longer in production. Until now, we had to deal with it by hand, but recently overseas repair parts have begun production. Cases like this have helped to raise the reproduction accuracy and reduce the cost.
After removing the corrosion and restoring strength, extra steps such as sealing and urethane coating for the body, powder coating for the suspension, plating treatment for the stays, etc. can minimize re-deterioration in the future. In addition, as the ultimate body regeneration technique, it can be sometimes possible to bring the chassis to the new car production line after-hours. Electrodeposition coating can be done in this case.
The financial cost of full restoration is a concern, but it is difficult to present a uniform standard because of the degrees of variation in the damage or corrosion depending on the condition of each individual body’s condition and the level of work required.
Even if the body is in a state that most would just give up and dispose of, Garage Yoshida will not overlook it. They will consider every possible measure to bring the car back to its original condition.
GT-R owners and lovers who have a desire to keep their car in top condition can now find the ultimate restoration method to save their beloved vehicles.
