Opinions or experiences on washing the GL1800 with low pressure garden hose sprayers? I'm thinking to try this for the outer painted parts (not the driver's zone or interior areas). I'd use a light spray just to wet and float away dirt; no high pressure blasting except maybe down in the lower wheel areas and inside fenders. So if I go about this with some restraint is it ok? Do you do it? Heard of serious problems from this?
