Rust on the B-pillar

Hello guys, I had the shock of my life today. Because the weather is today I had to swing the sponge today. After my TT was clean I found a small place rust on the B-pillar, right at the chromed temple where the door snaps in, at the driver’s side. I think the car is galvanized. Built 99 is mine, 4 years I have the. After 3 instrument combinations, 1 LMM and 1 thermostat, I am so slowly tired of. Has anyone else had the experience with rust? The handle is screwed with 2 torks. Alas, I don’t have any pictures, because I don’t have a camera.
