I had a lot of parts powder-coated black and the guy did an beautiful job. (Bill @ Ajax, right across street from TRE Motorsports). There are certain parts that should not be PCed because of the stripping method used which is media-blasting. Anything that holds oil, generally speaking.
Therefore, the axle tubes were hand-stripped with wire wheels, manually cleaned and painted. Same with oil-filler tube for engine, etc... Other suspension parts and all engine cooling sheet metal was PCed. I'll get pictures up of that stuff later, it's beautiful.
The inside of the torsion tubes have a light coat of surface rust, not bad at all compared to most original 356s but must be addressed, IMO. Who knows when in hell it will be back apart like this. After a lot of thought and some advice, I have a plan of attack for them that involves getting a wire brush inside and then painting the interior of tube with red-oxide rust-inhibiting primer. (Same as used on T-bars).
Here is the inside of rear torsion tube:
You can see the shot rubber bushing in this pic, original to car(?) We have all new ones plus new Konis in the box to install:
My first assault on the tube was to cook out any moisture w/ a heat gun, turning it on for 20 minutes and then off to cool-down, several times over a period of days:
