Undercoating...Yeh or Neh?
Do I or don't I?...I've heard that it's worse to undercoat than to leave it alone and just keep it clean. I never did it to anything else but my 86 Chevy completly disintegrated...just swept it into a pile and threw it in the trash. 
Trucks new so if I do it I would imagine that now is the time.
Ok, bombs away...

The people that had problems were because they were lazy. If you spray undercoating on over dirt and junk you will trap moisture and that will cause rust, if the are is clean and dry and preped right the undercoating works.

I'd say it depends on a few things:
1. the weather conditions where you live and travel (road salts? etc)
2. how religious and willing you are to get under the truck and keep it clean (be honest with yourself!)
Keep in mind that the undercoating is going to add a bit of weight. Check also Ford spec's on what treatments, if any, they apply from the factory to the underside.
Good luck,
Daryl

When I undercoated my truck, it was a lot quieter on the road. Don't know whether that matters to you or not. If I had it to do over again though, I would have had Line-X do it instead of the dealer.

Some areas have the high tech clear undercoat, it is very good.
Check it out in your town, maybe someone will have it.

Linex dries within 3 seconds or so of applying the undercoat. This is a great thing when you want to drive it away in about an hour after application. The other stuff needs to set up for an hour before they can do anything. Linex also takes the bolts, screws, and tiedowns in your bed off before they coat it. This means you can get into your access panel should your handle ever break and you can take your bed off if needed without destroying the liner. My Ford Ranger handle broke and I had to destroyer the liner to get into the panel. It pretty much sucked.

I had it done 94 ranger when it was new. I thought it help keep the under carriage in good condition. But at the time I lived in Central Illinois, where you had a lot of salt and raod grime in the winter time.

Hey guys keep in mind that if you use like a tar undercoating or some thing like that you can have worse problems with that kind of undercoating. Because they can rust from the inside out. That is why I recommend ATF I have used that for years and so hasn't a lot of people here and it works great. It cost me 45 bucks per truck but worth it.

I would say it would depend on where you live. I live in the midwest where they use tons of salt and it is hard to get my vehicles washed in the middle of January without having everything freeze up. So I just had my truck undercoated prior to picking it up from the dealership. I let you know how its working out in about 10 years. I am religious about keeping things clean etc. when the weather allows me, but like I said when it gets to cold that salt may set on there for a while. I guese I need a heated shop. Help me convince the old lady of that!
