The Art Of Blending Craftsmanship & Technology
Here at CPR....
We do our best to not only use our extensive knowledge of Porsche factory techniques but also the new technologies that are becoming available every day in order to put out the best product possible.
For example, everyone knows that prior to 1974 Porsches were not galvanized and suffer from rust which in many cases can be extensive. Much like building a house, the unibody of a Porsche is its foundation. If you don't first start with establishing complete integrity of the unibody, the restoration will never be right and the value of your investment will be greatly diminished.
Booth 1. This both is a standard back flow booth used for priming and component refinishing.
Booth 2. Our environment controlled state-of-the-art down draft booth. Here we can control humidity within 1/10 of 1 percent and the temperature within 1 percent between 70 and 170 degrees.
As a result, we can ensure the best finish by adjusting humidity and temperature to meet each product's specifications.
Built-in baking ovens allow us to cure the paint the same way it's done at the factory.
By controlling the environment we can control the flow of the paint producing a glass like finish minimizing the amount of color sanding required to obtain perfect results.
The first step in any restoration is to disassemble the car, removing the interior, trim, powertrain, suspension and glass.
Afterwards, the complete unibody, with all attaching panels removed, is stripped to bare metal. Any areas requiring rust repair are addressed by the installation of new factory-style panels which are welded into place utilizing the same process Porsche used when the cars were originally built. All welds are made 100% flush using the latest technology.
During a belly pan replacement for example, we are able to recreate the look as originally built. It is always our intention to make these repairs so that even the most discriminating eye cannot tell that the panel or panels have been repaired or replaced.
After any integrity issues with the "foundation" have been addressed, the tub is then coated with technologically advanced materials which have been specifically formulated to etch into the metal, permanently preventing any future rust issues. The belly pan, engine compartment, and front battery area are then coated with a special process which entails applying a rock-hard, paintable coating which looks identical in depth and texture to the original undercoating. Based on the owner's requirements, the belly pan is painted either black or the color of the car and engine compartment and under hood area is painted the color of the car or black, as Porsche did both depending on the model and year.
While this process is taking place, all component parts are taken to our mechanical location, where every part is cleaned and inspected and a list is established of all parts which will require replacement, replating, and repainting. Wheels are sent out for restoration.
The powertrain is separated and both the engine and transmission are thoroughly cleaned. The transmission is disassembled and inspected. Any worn components are replaced and the transmission is reassembled with new seals and gaskets.
The engine, prior to disassembly, is evaluated to determine the scope of its restoration. At the very least, all sheet metal is stripped to bare metal and coated to a finish which resembles the original look with ten times the durability. All external seals are replaced to assure a dry motor. Fuel rods, linkage, and connectors are replated and restored to like new condition. Although every car is different, it is always our intention to do only what work is necessary to bring the car back to its original look and performance while adhering strictly to the factory standards of quality. Should an engine need a complete overhaul, there are many performance enhancements such as forged pistons, new cylinders, strengthened case studs, upgraded chain tensioners, or uprated fuel system which can be upgraded at owners option to increase performance and reliability. However, we always strive to retain the original look of the engine so that these enhancements do not detract from the value of the car.
Once all paint work is completed and all components are restored, the car is reassembled using factory original seals, which encompass 95% of the required seals. The remaining 5 % is made up of high quality reproductions, as the factory seals have been discontinued. The suspension is then reassembled with new parts as needed, such as brakes pads, lines, and rotors, wheel bearings, and shocks. Once this is complete, the powertrain is reinstalled in the car and administered a thorough operational check.
At this point the carpets and interior are reinstalled. All systems such as wipers, heater, and air conditioning (if applicable) are then function-checked to assure that they are in proper working order. The car is then thoroughly road tested by our technical manager, an ex-Porsche factory representative with 33 years experience, to assure the car is delivered well sorted.
Sometimes it costs a little more money to have things done correctly. Sometimes, it is much less expensive to do it right in the first place. Here at CPR Classic our prices are always fair and competitive. If your Porsche is suffering, get it CPR!
