I have washed my MPS twice now, and both times I have managed to injure myself.
1st time was washing across the back bumper and the old little finger went into the place where you open the boot, where the rest of my hand continued forward, with the little finger bending backwards.. Few swear words later and one very bruised finger.
And today I was washing the exhaust extensions and manged to slice my finger open across the knuckle on the actual exhaust pipe. Its actually a sharp bugger.
So yeah be careful, and dont be a clutz like myself
Oh and BTW the car is ok!!
