I have SA 3 speed wheel from 1963 which I would like to true. The wheel looks like it hasnt been touched in a long time and the metal has sort of a white powdery look.
Before I go about trueing it I thought it would be good to lube the nipples so i dont strip them. I also know that ammonia removes corrosion from aluminum and penetrating oil removes it from steel.
What would you expect nipples/spokes from this era to be made of? Is my plan of lubing with ammonia/penetrating oil good?
Anything else I should look out for?
If I should be using penetrating oil does anyone suggest a brand or are they all the same?
