Geo,
The idea of a bed liner on the roof is an excellent idea from several perspectives.
"¢It is incredibly durable and UV resistant and color fast
"¢It seals up the entire surface with a flexible membrane like surface
"¢And it is a perfect non-slip surface to walk on if you load or use your rooftop for watching the races

On the downside, it can be hard on bare knees or rip the knees out of your favorite jeans ... a small price to pay for the durability.

I think I will add this to our project list when we finish the roof.

Thanks,

Jim
