You and me both. But after doing a lot of emergency repairs (kick-
ins) and replacements, I found that the insides range anywhere from
loose laid panels of styrofoam (sometimes glued to one side), random
squirts of urethane on the perimeter, all the way to solid urethane
cores.

I have even seen them where there is nothing in them except
materials
glued in place to stiffen them up in the center and at the door lock
hole. (Hint: When you see an $89 metal entry door, think of
this..)

IMHO, a solid urethane core should be the minimum specfication.

After that, look at the skins.

The material I am using is rated for marine use. It is a modified
urethane product, and you are right. It is perfect. It dries hard,
hard, hard. It is extremely abrasion resistant, and it looks like
it
was baked on in a factory.

High build epoxy primer followed by some good L/P which can be
applied
with a mohair roller and tipped with a good brush.

OK... now you overshot me. I don't know how to apply that stuff,
and
I don't know anyone that would pay for it! My favorite is about $55
a
gallon (Coronado "Corotile" from their industrial line) and is rated
for "medium" industrial use for manufacturing and processing plant
application.

I can't imagine what your stuff would cost or how much it would cost
to apply it.

About the only thing more expensive than marine L/P are aviation
coatings.

Before crude oil prices went bonko, good marine L/P was about
$200/gal.

You can apply it with a mohair roller (1/4" nap) on a phenolic core.

Based on your description, stick with what you are usingG
