Morgan wipers are renowned for their uselessness in the rain!
Over the last four years I have experimented with the angle of the blades, bending the arms to increase the pressure, rain-X or equivalent without any real consistency or effect.
The only thing that has been the most effective is to replace the rubber blades with silicone. These are cheap on ebay and do the trick.
Some minor mods to the fixings will be needed.
I thought it was only in England that it rained!
