waterproofing and UV protection for canvas

Canvas dos not need anything. If you want to spend money, 303 Fabric Guard works great. For UV protection, 303 Aerospace Protectant on everything outside my TT. Thanks for the reminder I'm due.

Awning material is not normally canvas, but amvinyl laminant. There is seam seal products, but like Bob said I have never worried about a few drips. When it rains, be sure to tilt the arms so water runs off.

Im probably going to go all around. Snowbirding.
I noticed that with heavy rain, I am getting some water penetration through the canvas awning.

Also with the UV, I want the canvas to last as long as I can. Ive heard its expensive.

Some of this depends on where you live. Our awning is 14 years old and we have never put anything but mild soap & water to it. Just now starting to crack this season and only on very top.
