Are all 928 bodies Galvanized? If not, what year did it start? | Thread profile

There are Porsche's and then there are Porsche's. Bodies for some models were made outside Stuttgart Zuffenhausen plant and this is IMHO very good explanation for different fully galvanized dates. 914 was made by Karmann and they probably didn't have facilities to do the job while '73-'77 period 911 production line at Porsche's own factory did. Similarly 924/944 series had partly different paint options than...

What year did they start galvanizing the 928? Are 78-79 often rusty?

H is right, the only rust you typically see are on cars that have been repainted and they were sanded to bare metal through the galvanization. The whole body of the car is steel of course and just the bolt on items such as hood, front fenders and doors are aluminum.

I dont believe all porsches post 1973 are galvanized, but all 928s are galvanized. I have owned several 914s and none of them have been galvanized post 73.

Right Lane (or is that Left Lane), I had a 74 914 2.0 liter that rusted out like an old garbage scow that had plied the salty seven seas. When I traded it in they had to come to my house and take it away on a flatbed truck. Joe Celeste Seminole, FL

From what I have read all Porsches from 1977 on were galvanized.

I have read both. ( [1] All Porsches from 1977 on were galvanized. [2] All Porsches from 1973 on were galvanized.) I read both those statements here in this very thread...which speaks volumes for the phrase "cite your source". ;-)

All years are galvanised IIRC. Very rarely rusty unless damaged and then repaired.

That doesn't prevent corrosion entirely though... Mine has several issues I need to get sorted this winter - doors, front fenders and around rear spoiler mounting (I have the "limited edition" detachable rear spoiler). Nothing that will leave holes anytime soon, but still.... Aluminum may not rust but it still corrodes, galvanized or not.

Hey Jim, did you sell your's or are you shopping for a new project? I was interested, but I think we've got to get an econobox instead. I've seen rust bubbles and cracks around an edge or a flange which is consistant with rust occuring away from the surface of the panel on galv metal. The water seeps under a seal or around the edge of a screw and gets into the tin, then the oxidation starts. Doc
