I am about to mount corner guard armor and rocker rail on my project TJ. The last rocker I installed years ago became the source of mud and sand trapping an ass ton of rust. I have spent the last 6 months mitigating rust. I don't want to cause more problems in the future mounting this armor if I can avoid it. I am considering a silicone or perhaps a 5200 coating to seal it. Any experience or advice would be appreciated.
