hey guys winter is almost here and here in michigan the roads get pretty salty and i want to protect my almost rust free undercarriage. whats the best stuff to use? bedliner or undercoating? and which brand is the best? thanks guys

 

Bedliner I like the rustoleum aerosol truck bed liner

Undercoat I prefer the aerosol undercoat made by HiTech Industries.

 

Sorry for the sideways pictures

 

For bed liner I like the Dupli Color brand. Really nice stuff

 

What do you think would be best for under there? Bedliner or undercoating?

 

A undercoat for sure. Any kind will do really. Just makes sure its clean and any surface rust needs sanded

 

thanks, does everybody else agree a undercoating would work better than a bedliner?

 

That's pretty much what it's made for. Plus flying rocks will chip the bedliner to pieces. I say undercoating

 

I like to ospho(rust converter) everything before I undercoat.

 

is the duplicolor undercoating any good?

 

I like it I did my floor in it there are some picks on my build thread I think but I use cassis saver on everything underneath and have never had an issue the kind I use is made for tri-axles so it takes a beating

 

I just used the stuff I found at walmart and it seems to work fine. It took 3 cans to do one coat on my WJ, so that should give you an idea how much you'll need.

 

thanks guys. i bought some duplicolor undercoating from napa today, they had it on sale for 2.69 a can. i got it all prepped and ready for the undercoating tonight. will spray it tommorrow

 

Just about to apply some undercoat. The NAPA guy told me that I could spray the duplicolor undercoat directly onto rust and it would seal it (after scraping the rust flake off). Is this true? Do I need to prime with anything first?

 

Por 15 is the best stuff out there
