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.
At Restoration Design, we specialize in restoring Porsches from almost all years and models. And while we’re experts experienced at this, we still learn lessons from every project we take on.
When we restored Mike’s 356 Speedster a couple of years ago, we learned a few things that have stayed with us and that we have applied to every project since.
Measure, Measure, Measure
The most important thing we found was to measure frequently, almost obsessively. Especially when it comes to sheet metal pieces, it’s not uncommon to do many trial fitments to get the right fit. When it comes to the doors, it’s important to have all of the rubber pieces in place as well, so you know everything fits as it should. This is true for any kind of automotive restoration.
356s were produced in two different production facilities, so some parts might differ – that’s why measuring is so important with these models.
Have a Camera on Hand
Keep it in the shop and take pictures throughout the dismantling, so you have something to refer to when you come to put it all back together.
Keep a Parts Catalogue
Go through and take note of the parts you think you need, and if you don’t need them you can cross them off.
Set a Restoration Quality
Before you even start on your vintage Porsche restoration, decide whether you want your Porsche to be concourse, show or driver-quality.
