Plastic swing arm bush "upgrade" (with pics) (2015)

If you use a steel pivot pin dry or with no oil due to not refilling it often enough in time rust will form. This causes expansion of the pin (just like in reinforced concrete when it brakes apart) and a rough surface that eats the bush be it plastic (i once had RD350YPVS that did just that) or metal. I have just renewed my bushes and pin with original type and have a tight fit just the same as your new plastic type. The oil is not only to lubricate but to prevent rust so it is important to keep up with adding it regularly.
Or you could try a stainless pin but just as with the plastic type used to make the bushes if the wrong type of stainless is used then thing could go badly wrong in this highly stressed and vitality important fixing.

Could a layer of grease on the pin prevent such rusting? Stainless pin?
