Can anyone tell me what the original coating was for the horns? Most of the ones I have seen are painted...with overspray. (IMG:style_emoticons/default/dry.gif)
Thanks to a pointer in another thread, I have managed to get the ones from our 914-6 working again. Despite several searches, I've yet to find a resource that indicates the proper coating after stripping the cover and the diaphragm.
Ours prior to stripping didn't offer much evidence to guide me. Attached image(s)

QUOTE(aturboman @ Apr 19 2023, 09:01 AM)  NOS 914-6 horn for reference. thats the first one i have seen out of the box that has not been polished up. (to remove aged galvanising oxidation? - which can occur even with a stored item). pretty much settles it seeing one in that condition. unmistakeable original galv mottle. the black stuff i am seeing on mine must be galvanised coating that has reacted to acidic water. generally speaking its rare to see galvanised coatings go black in australia. mostly they just dull off. though i am also of the opinion that some batches of these horns may have originally been painted. my old squareback def had a fully black painted horn and it was not an old or repainted restored car back then in the 80s. i was the second owner. maybe aus cars got a horn produced from a different factory or got a different spec. it was the exact same horn as the one on my 914. but looking close again at the one on my 914 through the bumper grille its kind of undecideable. it could easily be reacted galvanised coating. |
