Rust protection for the frame

Hello

Have you ever considered to spray a paint or a coat under frame to protect it from the salt and so diminish the risk to rust it?

If so what coat? Line x? Or a special spray paint that could be applied by ourselves?

 

I would never use a rubberized or tar undercoating or bedliner type product. When it gets nicked and dinged, which it inevitably will, rust can start and work under the coating and hide while it does it's dirty work. Plus it's very hard to get those products directly into tight and hidden spots where corrosion often starts. Instead it may be better to use an oil based product like Fluid Film that creeps into the nooks and crannies but has to be reapplied each fall.

I just went and bought some CorrosionX HD locally at academy sports. Looking forward to seeing how it does.

 

I disagree (at least with respect to tar undercoating). HOWEVER, I do understand where you are coming from on this.

The problem with these coatings is that they typically aren't maintained adequately. They dry up, possibly crack, possibly dinged up, and expose access to metal.

However, if properly maintained, they provide a superior rust protection than anything else.

And by "properly maintained", I mean periodic application of oil to the tar, and occasional respraying as needed.

If you keep the tar oiled, then the tar remains soft, AND the oil is impenetrable to water and everything else you want to keep away from the metal. Essentially, periodic oiling provides you with a THICK oil coating, and a THICK oil coating is a lot better than a THIN oil coating that gets immediately washed off (like fluid film).

I use a schutz gun to spray chainsaw bar oil on it every year. Bar oil is also waxy and likes to stick around.
