Altrider crash bars coating

[siroco]

Hello everyone,
The powder coating on my Alt Rider engine guards started to peel off on its own; So I removed all the paint with shot blast treatment and then primed and painted them again.
The thing is that now I like the natural satin look without the paint but I don't know if I can leave them like that, since they are T304 stainless steel, which theoretically does not corrode.
I wonder if the silver versions of the Alt Rider crash bars have some kind of treatment or are they natural? Thank you.

But the question is if it is possible not to paint, I would like to leave it without treatment. I need to know if the silver one comes with some type of coating or instead it comes sand blasted only.

Just use a satin, or maybe matte, clear coat. Hot rod guys do it all the time. They want a patina look, but don't want the rust to keep growing. They clear coat it.

If it's definitely stainless steel, you don't need to paint it. Painting may actually make it less corrosion resistant. It can be painted with the right technique, but if you like how it looks in its natural state, it's fine to leave it that way.

My Altriders are plain stainless matte finish. There is no factory coating applied in the way of painted on finishes. Just a plain non coated surface.
Passivation may have been carried out at the factory.
Stainless steels will pick up iron particles during the manufacturing process from equipment that may also process alloy steel.
The passivation is an acid wash that dissolves any surface iron particles and prevents the rust spots the iron will cause.
If you care about or expect this iron particle contamination you should read up on passivation. There is info aplenty on the internet.
Citric acid was what was used in the plant where I was employed. A relatively benign process involving a heated bath with positive ventilation.
There is also a nitric acid process. Avoid nitric acid if you will be attempting this yourself, even the fumes are problematic and must be avoided.
All the best.

Thanks for all the answers. At least I will clean with an oiled clothe frecuently.

304 is generally passivated at the mill. If you media blasted it you likely removed the passivation. No big deal. The brightness will dull over time but it will be gradual and unnoticeable. Hit it with a brass brush and it will brighten up again
