Had a windshield wiper fail when I pulled my RV out of storage before I headed South to the FMCA Big convention in Perry, GA a few weeks ago.
Why did it fail? It got old, just like tires do. Also I failed to protect the rubber blades.
So yes this is a situation of do what I say not what I do. So how do I protect my rubber wiper blades? I got some white vinyl table cloth material, cut it and hot melt glued one edge.
This should give an extra year or two to the blades.
