Huh? Don't you just wait for the next rainstorm, then go for a ride??
That's what I do, only if I'm 'washing' the Spyder, I won't go play in the mud like I'd usually do, just take a bit of a run around the local streets and then give it a quick blow dry with the leaf blower and rub-down when I get the Spyder back into the shed - bike all washed and lookin' spiffy!
And if it's the right time of day, with not too much other traffic around, no kids on the streets, and I reckon I can get away with it, I might even have a cold shower while I'm out there...

Not if it's too cold of course, or if it's absolutely pelting down with rain or hailing either - you don't even hafta be going fast for
that to hurt like buggry on bare skin!
