Undercoating

[MacDR50]

Winter is almost over here and the frame of my shiny 2008 is looking worse for the wear. Loose paint and rust spots. Anyone have suggestions for a good frame coating? I have the rest of the vehicle rust proofed but the frame doesn't seem to have benefited much.

Used to be that GM used a waxy sprayed-on coating that held up pretty well. If your coating is peeling in places, just use a powerwasher to blast the loose stuff off, then get a rattle-can of auto parts store undercoating to touch it up.
