Hi Julianna,
Interesting application for a truck bed liner.
Actually, I'm preparing my van for the same thing. I'm tired to the death of the
rock pounding the front of my van has been getting.
My son, who operates an bed liner outfit in Birmingham, AL called Defender
Coatings, will do the job. He doesn't use the conventional polyurethane
coatings, but uses a second generation product - poly-urea. It's been around
for 60 years but only recently has the technology been available for its
application. It is applied at 150 degrees and 2500 psi. Really tough stuff.
This is what will go on my van.
To combat fade, I'm having an aliphatic added to the mix which will prevent it.
Otherwise, like polyurethane's, it would fade to a shade of gray or whatever,
depending on the color. This poly-urea is some kind of tough stuff. I saw a
video where a coating of the material was applied to a sheet of foam insulation,
then a 2X4 was air blasted end first at it at 150 mph. Just bounded off. So it
should really help deflect the rocks. Of course the metal under it may flex a
bit. But it really takes a hard blow before it tears. And of course it won't
chip. Like yours though, the substrate has to have a good scuffing before the
application or it would peel off in a big sheet. It won't flake at all.
My application will be to the front, the two long low panels between the front
and back wheels, and the wheel wells. Prep in the wheel wells is going to be a
pain, and I'm not sure yet how it will be handled.
Though is can be applied smooth as paint, I plan to have a very fine stippling
applied to the surface.
Will post a picture when it is finally done.
By the way, my son also uses the same bed liner Poly-urea for roofing on
commercial buildings. After prep, it is sprayed and built up to the specified
thickness. It then serves as the roofing membrane. Lasts for years and years.
What makes it nice is it can be sprayed over damp spots in old roofing without
problems. Do that with polyurethane and the stuff swells badly. Ever see the
foam insulation that comes from a pressurized can? Most of the time that is a
polyurethane. What makes it foam is the water content that gets released. Swells
and bubbles like crazy. Very damp at first but eventually dries out.
Enjoyed the picture!!
