Undercoating, what to use?

[ThatOneKid]

Hello all,

Ive been wanting to spray the underside of my truck for some time now, as the paint on the frame is beginning to chip off and rust.

My question is, what is the best substance to use? bed-liner, or some sort of rubber in a can? And also while im down there, anywhere else I could cover up?

Thanks!

If you look in a local parts store you should see something specifically for undercoating

Ditto what Zora said. Autozone and Advance both sell the spray on undercoating for around $7.00 per can. I think that price is close, but it could be higher!
