In 2013, we decided to restore a 1972 911ST – our first!
The project started off the same way most restoration projects do: we sanded the body down and realized there was more rust damage than we had anticipated.
The sanding also revealed that the 911 had been in a front-end collision, meaning we had to replace the entire inner fender.
This model of Porsche didn’t come with proper ending panels and didn’t have rock guard, so we would be doing the same with this restoration.
The ST we purchased was produced for racing. While American race cars were building bigger engines to win races, Porsche increased their horsepower and made their cars more nimble and a lot lighter – which proved to be successful.
These models also didn’t come with ashtrays, glove boxes, the heating and ductwork was removed and the gas tank fill was located under the hood.

Back in the fall of 2007, we noticed a substantial need for hoods for 356s. Getting a good quality hood was pricey and often difficult. So, we decided to start making them ourselves.
To start, we purchased one of these good quality hoods from the US. Painting it matte black and getting some of the minor imperfections out made it possible for us to use this as a template for scanning.
We got the scanning done by a third-party, who then sent us the scan. We imported the scan into our own computer system so we could design the dye. Designing each dye typically takes 100-200 hours – just for design time.
After the dye was designed, we had to design the different tool paths for 4-6 different tools.
From there, we had to machine the dye using steel and composite to withstand the pressure of the press.
After the dye is machined, it needs to be polished. Polishing the male and female parts of the dye for the 356 hood took about 16 weeks in total.

At Restoration Design, we often get questions about the kind of steel we use.
We use galvanneal steel, which is used in a lot of industries, with the biggest being the automotive industry.
A lot of other restoration shops use mild steel because it’s more cost-effective, but we prefer galvanneal. It’s also better than galvanized steel because it goes one step further in the production process: after it’s coated, it’s heated at super high temperatures, resulting in a higher corrosion resistance than other kinds of steel. This also means it has a longer shelf-life.
The main reason we prefer galvanneal steel over galvanized steel is that galvanized steel’s coating will flake, and galvanneal will not rust when exposed to water.
Watch our video to find out more about the difference that using galvanneal steel makes, and see some examples of Porsche restorations we’ve used galvanneal steel on.
