rhino lining?

Hey guys I'm pretty new, bought my truck in SOCAL and then drove it to GA. The previous owner had the truck for 68k miles and drove to costa rica a lot. I haven't had time to R&R since I've been deploying so much. The undercarriage is pretty rusted I'm pretty sure its from all the salt water. So I was wondering if anyone on the forum has had success rhino lining the bottom of their truck? Also the truck came with the TC & Icon Mid travel set up and the ball joints on the Upper Control Arm are a little rusted too, i was wondering what people did to try and lube them up? Just curious, thanks

 

Whatever you coat it with you'll still have to remove all rust before hand.
