Default Polyurea Coatings

I'm a lurker here because of my fascination with all things Newell. Reading concerns about finishes for bays and waterproofing roofs, I wonder if any of you have tried a polyurea coating like LineX? http://www.linex.com/

Polyurea coatings are nearly indestructable, and can be applied as a foam or a thin layer. Sometimes used for blastproofing buildings too. Anyway, you all have seen truck bed spray liners. The best are polyurea. They come in any color, but are less expensive in black. They can be applied smooth or textured.

Since polyurea coatings are used to protect industrial roofs, they would be great to repair or seal an RV roof. They form a permanent bond to the aluminum skin and to any roof penetration.

You can get home applied truck bed liner coatings, but they aren't anywhere as durable.

I have no financial interest in any coating company. It is just that I have researched the products at length for waterproofing buildings.

One more thought: There are discussions about damage to the finish for Newells, and all RVs for that matter, from road debris and tree limbs. Applying a polyurea finish to areas subject to damage will eliminate the concern. Lots of guys with hardcore off-road Jeeps spray their entire vehicle with polyurea to make the finish very durable.

How smooth and shiny will it be when sprayed?
Wouldn't want to mess up my shine but rock chips get pretty old.

The samples I've seen are either shiny and smooth, shiny with a surface like an orange or flat and textured like a truck bed liner. They can color match too.

Here are some LineX photos: http://www.linex.com/gallery/list-image.php?=&album=28

The stuff is tough. Here is what the industry says about it:

Polyurea protective coatings are commonly used for the following reasons:

Abrasion Resistance
Corrosion Protection
Waterproofing
Chemical, Environment or Atmospheric Resistance
Decoration
Structural Enhancement

I wouldn't cover an entire coach. But to protect or seal a roof, the bays, or to repair damage from tree branches, I think this might be the ticket.

What I will look to see is if it comes in clear.

In addition to durable coatings I see so many trees overhanging roads and think that a RV A/C unit or dish would not survive the encounter. This make me wonder if there are roof mounted protection bars or cages available.

Maybe I'm crazy, but I think that there are times when a tree branch rubbing the roof of an RV is unavoidable. Why not take a page from the off-road community and add a bar to deflect tree branches up and away from the expensive equipment on the roof.

I like the smooth finish our roof has. The smoother the finish the more reflective.
I would be concerned with a coating like this. If it were to allow any moisture to be trapped, it could really create problems with the Aluminum. Besides I am not so sure that it would look correct.
