DPeterson3 In aircraft work it became popular to use soda stripping as it was much quicker than chemical. However, we learned that this destroyed the pure-aluminum coating on the alloy underneath. This pure aluminum coating is to improve corrosion resistance, as the common alloys are much more prone to oxidation/corrosion of various sorts, even though they are much stronger than pure aluminum.

The type of corrosion that forms on aluminum can be quite varied, depending upon the nature and quality of heat treatment and alloy. Generally, the corrosion doesn't begin to be easily apparent for many years and even decades. This may or may not be impacted by dry, warm storage, as some of the corrosion can be purely a function of heat treatment gone wrong + stress. Excessive working of aluminum can speed up these types of corrosion (which is almost an incorrect term), so as Bernhard notes, if you don't know what you're doing you should keep your hands off.

touring63 hello,
we clean last time aluminum with dry ice and soda.
the next project - cisitalia we clean the body and frame with new special high pressure water methods in italy.
this firm work for the ferrari-factory and another high class alloy cars and has experience in the sensitive handling of the alloy.
fine cleaning and finish all with hand.
you can not work so much on filigree thin old alloy with machines.
does not break hardened alloy you must work with a clear head and tricks
if you've never worked with aluminum better then the fingers away.
you can irreparably destroy the body in the assembly.
the transport from usa is no problem.
price tour- retour from los angeles usd in container 3500 USD.
best regards

alfa_corsa Bernhard,

This is truly inspirational work. I own #10321, the younger sister to the car you're working on, and which will also need some bodywork/fabrication to correct poorly executed repairs done on the car decades ago. Sadly Los Gatos is very far from Graz.

I'm curious what method you used to strip the paint from the aluminum. I assume you used chemical stripper? I imagine that sanding or abrasive blasting would surely destroy the aluminum skin.

Super1600 That is fabulous craftsmanship Bernhard. Zer wunderbar !! I hadn't even realised this model was of Superleggara construction, but I guess in hindsight am perhaps not surprised.

I look forward to seeing how this project continues on towards its completion, I am sure it is going to be superb.

Original colour is grigio biacca but I prefer the dark blue colour like Bleu cobalto. I just started to think about.
Master Bernhard has done an excellent job, Im very happy about it.

Josh Beautiful work. That's an impressive skill, to do it like they did originally.

I imagine that unfolding the aluminum panels from the steel framework, and putting them back on, without damaging things too much, is very challenging as well.

Subtle Impressive restoration.

touring63 thank you for the compliment.
i m learn this so to manufacturing high quality prototypes and making special bodyworks and so is looking professionell finsh.
so can better find the lines if you want to work as possible without thick layer filler.
