Re: new jeep - mastershield undercoat
Hey Snow! Yes, the steel is thinner today, but it's made of High
Strength Steel which is much stronger and lighter than the older sheet
metal. The automotive steel is treated for corrosion/rust MUCH better
than in the past. Zinc baths and primers make a huge difference.

That rolling/lipping/stamping creates a nice pocket for moisture and
more importantly tiny bits of organic matter (like dirt from muddy
water) to get trapped in, which then does a superb job of keeping water
in contact with (in the case of old cars) un primed, untreated sheet metal.
Those rolled metal edges are usually among the first area's that need to
be cut out. Classic cars often have there worst rust in the lower doors
(rolled seams), the floor pans (un treated/unprimed underside, often
with a bad undercoating job which accelerates the rot by trapping
moisture against bare metal) the rocker panels which have lots of
moisture trapping spots usually a lip under the car or a spot welded
seam where the floor pans meet it. The lower fenders (usually a lip).
More modern cars seal the rolled seams of the doors and the sheet inside
the door is usually primed, then there's splash guards in the wheel
wells to keep water/crud off the lip of fenders.

Right you are. The galvanized primers and wax injection prevent any small
bits of corrosion from ------ing. That's why you don't see newer cars with
rotted wheel wells, rocker panels, etc.
1973 Chevy pickups, Ramblers, etc. aren't considered "newer"!
