Hi everyone. I have a question regarding when to apply fluid film to protect my TJ frame. I plan to spray the inside of the frame rails before the winter to prevent corrosion. I just purchased a kit with a spray gun and will be doing this for the first time. I plan to go wheeling a few more times before the winter and am wondering If I spray now, do I need to re-apply after rinsing out the frame rails after wheeling? Does the film remain after rinsing a few times or does it come off with the mud and water? I already drilled holes in the bottom of the frame to aid rinsing. How often should I re-apply?
