The guys at Airgas told me the red fuel hose on the exterior of the studio will more affected by UV light than weather and temperature changes.
I use a pool noodle to cover and protect my hose.
Using a box cutter, I slit the pool noodle lengthwise on one side only.
This allows you to slide the pool noodle over the hose so it is inside the hollow center of the noodle.
I cut the end of the noodle to fit the exact length of the hose.
Then, I use a few zip ties to secure the noodle closed, seam side down.
I write the date on the noodle with marker so I know when it was changed.
I replace it every fall.
Fast, simple. And, the hose underneath feels and looks like new!
Inexpensive, too! (Not to mention COLORFUL!).
