Covering the awning with a black cover will only make it hotter in the sun, making it counterproductive
And a petri dish of mold, because of the extra heat.
C'mon guys, I live in south west Florida. Had this on all through rainy season in the sub tropics. My awning never even needed cleaning. If you choose not to use it, fine. It is posted for the benefit of anyone who chooses to use the information. Isn't that the whole idea of this forum. I have learned a lot from people here, and appreciate it.
Come up with something better.
If you are just looking for an argument, have a nice time, let me know how it came out, I won't be there.
