OK I know this may be a volatile subject, so before I get flamed please consider my specific situation -
My M1028 sat on a National Guard Base in Arizona for 25 years before I got it. It had, and still has, Zero rust on the underside. In fact, the underside of the cab looks almost new.
I am preparing to install the auxiliary tank and replace the OEM tank, and want to apply something to the cab bottom before lifting the new tanks up in place. I want to apply a product to achieve three goals - 1)- to coat the underside to prevent any rust from ever getting started, 2)- to reduce road noise, and 3)- to improve insulation value because I am planning to add A/C in the cab. I understand this issue has been debated on this forum several times before, and in fact I believe it may have even made it to the floor of the U.S. Senate with no resolution. Maybe this time we all can come together and agree on a product to use.
I have looked at Lizard Skin, however I do not see how such a thin coating can provide much insulation. I considered LineX, but I need a product which I can add a little here and a little there over time, so I need a product off the shelf in rattle cans. If a GM dealer were to undercoat a new Chevy truck, what would they use? Ideally, I want a product that can be built-up to a thicker coating than just a film. Once the new fuel tanks go back in, they will not come back out, so whatever I am going to use needs to be applied now.
I would appreciate responses from guys who have had experiences with undercoating, instead of opinions or left-field suggestions from non-experienced folk. Hail I can Google as well as anybody. Just remember this - I am going to use something, so don't try to talk me out of it.
Anybody had any experience with undercoating?
