I did it on my Jeep wrangler (sold) and like it.

i m curious any one of you used it for your truck (under the fenders and frame etc ??) ? Due to winter salty on road or beach 4x4.

I want to do it for my 04 FX4 F150 truck pretty soon.

Is there any spcieal can rattle spray is good stuff??

I know Hercuiler stuff but its pain in the butt .

Thanks!

I like using 3-m rust fighter II . It does a good job getting into the seams & wont clog up the weep holes. Costs a little more than the regular undercoating, but worth it IMO. You can usually get at most auto supply stores.

 

Never heard of 3-M, whats it excalty? is it like a rattle can spray??

What auto store that carry it?

I ll try do some search thru google..

Thanks!
