Hello Folks!
I am a first time Ford owner and just recently purchased (about 3 weeks ago) a 2K7 F150 XLT 5.4L Triton SuperCab (Charcoal). At the time of purchase i also opted in for the xiamize protective coating for the exterior & interior of the truck that the dealership offers, I took it in today to get that done as a matter of fact. I am now wanting to get an undercoat done on it as well, there is alot of moisture here is Idaho and with the winters being as they are and the kind of terrain i usually drive in i thought this may be a good idea to get done. However, i dont know much about what i should be looking for when shopping around for an undercoat. I know that the dealership offers an undercoat that i think has a warranty for 10 yrs and it is about $295, but i dont know what product they use and if it is any good. I been reading through the forums and have seen that alot of people recommend the POR-15. Is this the best around? I am planning to call a few places to get some quotes but i want tobe able not to only ask the right questions but know what a good answer should be. For instance, should the undercoat be warrantied for life? how thick should the coating be, is there a standard? what underparts of the truck actually get undercoated? should i be worried about the undercoat coming off if I later on decide to pressure wash the underside of my truck? what are some of the products that i should stay away from? and what are some of the good ones? how much of the undercoating solution needs to be applied (1 gallon? 5 gallons?)? how much is a reasonable amount to pay?

Also is this something that i could potentially do myself? is there a good how-to on this somewhere? and if i could it myself then how much do I need? what do i put the undercoat on (the entire power train?)?

I would really appreciate any help that you folks could provide. Thanx!
