I will not be participating in this forum as of 8/31/2018. It's been a fun ride, but it's time to move on. Take care. - Dustin

I used to have an old TJ which have been notorious for rusting on the frame. Does anyone have any recommendation on undercoating for the frame on new JLU's?

Quick and cheap. https://www.amsoil.com/shop/by-prod...s-and-protectants/heavy-duty-metal-protector/

I have sections of my undercarriage on the Raptor sprayed with it. Maybe spray it once it a year, if necessary. Seems to be holding up pretty good since UV rays can't get to it.

If you want the ultimate protection, you can go the POR 15 route. Needs major prepping and it's super messy. Once it's on, it's on.
