Rust layer after 6 months
I bought my 231mm tundra calipers from Advance auto parts and after only 6 months there is a good layer of rust, which I thought was surprisingly quick. Granted I did take it out in the snow a few times so that probably accelerated the accumulation.
I hit it with a steel brush and it slowly starting coming off - patience is required here. It seems to only be on the surface which means the original coat of paint is doing it job.
