Undercoating - Foam in doors/rocker panels

[SPD6IX]

Hey All,


I need to do some undercoating to my 08 LT, but need to find out what might be lurking for me in the doors/rocker panels.


Is there any sound deading material that I may have to deal with?

Or is everything hollow throughout the car?

My 08 didnt have anything in the panels so I highly doubt yours would be any different

I dont think your going to have any problems but i wouldnt suggest undercoating everything. Im a body tech and I see this stuff everyday and in my opinion I think that undercoating holds more dirt and water and causes more rust than it stops.

but thats just my opinion.
