I'm getting ready to apply poly-urea liner material to the exterior of my
van in strategic places. Poly-urea is a second generation material that is
the competitor to polyurethanes. Can be applied over a puddle of water and
it will set. Polyurethanes under those conditions would rise and swell like
bread dough. Urethanes used in expanded foams utilize water to get the
expansion.
As for my van, it is red, or actually burgandy, in color. The front end and
the rocker panels along the bottom edge have really taken a beating from
rocks and gravel. I plan to apply approximately a 1/8 th inch black
coating on the front end and the rockers. On the rockers it would come up to
the height of the fiberglas wrap-a-round bumpers that are on the GL. This
material is incredibly tough, yet flexible, and should provide considerable
rock protection. Preparation is to scuff the surface well the apply.
I had not thought of the wheel well and undercoating possibilities. I am
going to take a long hard look at those possibilities as well. With proper
preparation, I would think this product, or others similar would protect and
prolong the life of the vehicle by preventing/reducing rust by preventing
the entrapment of water, salt, etc. Of course if you live in the northern
climes as I did for many years, nothing beats a good hose job with a high
pressure wand at the local car wash to remove the salt/sand/crap that
accumulates in winter. This poly -urea is applied at a pressure of
approximately 2500 psi and sets in 8 seconds. Currently my son runs an
operation using it for liner applications and roofing membranes on
buildings. Pretty versatile stuff.
This is the same material that the auto industry is using to make the
flexible bumpers, fenders, splash pans, etc, that are found on modern cars.
