Under body coating

[Condor120]

The question I'm asking in this thread is What kind of Undercoating does anyone recommend? I'm planning to coat my Grand Prix's whole underbody before this winter, and I'm looking at a 1998 Grand Prix GT sedan for a daily driver and I want to stop any rusting that will accumulate

covering up rust won't stop it. However, I personally have not heard/seen anyone doing this in the few years I have been in the GP scene. I say fix your rust, then paint it. No need to spend unnecessary money.

ive seen people use bedliner and heat paint. it doesnt cost THAT much. hardest part is prepping and cleaning. rust only comes whens theres oxygen. so if you prevent oxygen, you prevent rust. also helps with road noise. only thing that bothers me is having to replace sh*t. bedliner is a b*tch to remove.
