My Alps Mountaineering Taurus tent has a rain fly with a slit-shaped window made from clear vinyl, similar to this model tent . It's seen little use, so the plastic isn't yellowed or aged, but the plastic has cracks. These allow moisture in and drips inside the tent.

I contacted the manufacturer: tent's discontinued, replacement is a reasonable $35, no warranty assistance offered.

Has anyone repaired theirs? The entire fly is in perfect shape except for the vinyl. I suspect if I shell out another $35 it will do the same. I'm thinking about a strong, clear tape I can place along the entire window to reinforce it or prevent further cracks.

Thanks ahead of time.
