2019 Frame Rails

[Shotgun64]

Hi guys, just bought new 2019 Sierra truck. I was wondering what is the best option to protect the wax coated frame rails???

Suppose to bring it in next week for paint treatment, rust proofing and undercoating. Ming didn't want to do the rails because of the wax?

 

Thanks,

Just keep the coating maintained with X-121 and you're good. Don't get too aggressive with the pressure washer on it. Just keep it well rinsed off in the winter and fix areas where the coating is damaged. Usually when the truck is put on a lift, the coating will get smeared or rubbed off underneath.

AMSOIL's Heavy Duty Metal Protector is a good product to use to keep the frame from rusting.
