During a severe rain last week our 4588 developed a leak at the bottom of the hatch leading from the pilot house to the flybridge. I cleaned out the weep holes at the bottom and that seemed to help for a while. The original gasket has deteriorated a over the years and needs replacement.
It looks like common weatherstriping but I don't think 1/2" weatherstriping will make the turns around the radius ed corners. Has anyone had any luck using weatherstrip as a replacement and, if so, how?
Does anyone know who made the hatch, and if gaskets are still available from the OEM?
