About the only thing undercoating has going for it is that it affords
a little better sound insulation from outside noise coming through
from the undercarriage. The thick layer can often dry with air
pockets in it or air pockets can develop with age ( stone dings,
shrinkage etc.) along with other gaps and holes from regular abuse.
These holes, gaps etc. allow water and/or water vapor a place to go
and once in it is not easily removed. We all know that if we can't
get water ( and any dissolved salts in it) away from a metal surface
very well, rust will get ahold of it. What's even worse is the fact
that rust can get started but is masked by the undercoat until
deterioration is huge and unfixable with just some sanding/grinding
and primer/paint. Big problemo! Stay away from that stuff would be
the advice I give. If you want sound insulation, do it from inside the
cab.

Welcome aboard Matt and congrats on your purchase. Even though it's a
sixer I think you'll be pleased with your Kota :-)
I don't have any hard and fast documentation to go by, so this is sheer
opinion/speculation, but I've been told so many times that undercoating is
a waste of money *and* is sometimes counterproductive (I.E. things rot
faster) that I don't even consider it. I've never had an undercoating put
on any of my vehicles and I've never had a problem with things rotting out
underneath... What I have done is made sure I spray out the undercarriage
after I've been 4wheelin' or driven into the ocean... That's not a typo, I
was having some fun on the beach with my old jeep when I caught some deep
water that pulled me in... still don't know how I got out but I bet those
Cali boys & girls have never surfed in a Jeep :-)
Anyway, nice to hear from someone else from the Boston area.
T.

I used to be a heavy proponent for undercoating. I had planned on having my
'96 undercoated until I spoke to the people at my dealership. They offered
undercoating and would have applied it, but advised against it. The
underside of the vehicle is coated with a "wax type" corrosion protectant.
I did not have the undercoating applied. Like I said, this was in '96.
Only time will tell.

Hey all,
I just bought a black '99 sport with the V6 3.91, standard, regular cab, no
toys except a CD changer. My question is in relation to undercoating the
wheelwells. What are the current opionions on it and if you are in favor, what
kind of undercoating do you reccomend. One of my buddies says go for the
undercoat, but my dad (who has been in the coatings industry for years) says
that the undercoats actually trap moisture which causes them to corrode
faster....Since I'm from the Boston area, a good undercoat that doesn't
promote rust I think would be a good idea...Any ideas....?
Thanks,
Matt
