    Default undercoating?

    hello.. i have recently moved to michigan from texas and i have a clean 89 shortbed that has no rust. i have the bed off right now for fuel pump change and i was curious if anyone could tell me a good product for undercoating before i get the bed back on. ivew never had to worry about the rust but i see all the vehicles here are eat up with rust and i cant do that to this truck its in too good of condition. thanks

    I like por15, it's held up very well from all of the Northeast winters here in NJ.

    3M makes undercoating. Make sure you clean everything from the bed underside and its dry before applying the undercoating.
