Rust where sliders cover frame?

Anyone have rust on the frame where sliders cover the frame?

did you use fluid film, surface shield , etc?

 

I used a light coat of Marine grade grease on the frame before installing the Sliders.

 

I used woolwax liberally before I mounted mine. Their coming off this summer to get refinished. I sure hope it kept rust off the frame! I’ll post results if I remember

 

Thanks! That would be awesome to get some pictures of what the frame looks like when sliders come off.
