what has everyone done to there frames as far as rust protection goes? the frame on my 03 TJ isn't to bad, with a few minor surface rust spots here and there, but i don't want it to spread like wild fire, like what I've always heard jeep frames do.
I was thinking about using a rust converter then either undercoating it in the fall or use a spray on bed liner right after the rust converter. the Canadian tire by me has all three products (rust converter, undercoating, and bed liner), the question is, what would be the best, and most efficient.
I use the TJ mostly as a commuting vehicle, but I also play a bit in mud/sand on the weekends, so i don't know if the undercoating will hold up good enough.
