Front / rear shock threads rust

So, I’ve had my new Tundra for just over a month (1400ish miles). I’ve noticed the threads on my front and rear shocks are rusting. Is this normal? I live in SE GA.

I read in another post that the front one is prone to rusting. Was more curious about the rear.

Thanks in advance!

 

A little spritzing of fluid film now and then will make all the difference

 

Thanks. I’ve picked up a can.

 

All of us that live where they salt the roads in the winter are just dying inside right now haha Your truck will be fine

 

I know I’ve got it nothing like you guys up north, but was surprised none the less.
