William Thanks for the Thread compliment..Thanks button is on the right side LOL...
Especially in winter, I am not gentle with the power washer ..My boat needs to be salt free whenever possible.
The 4 areas I really don't blast hard are wiper motor, fuse block, (cover ALT) and careful around fans, not to get water in back of fan motor so cover them too if u are going to blast the blades.
So dont worry..I do this often, start the car up, and go get it dry by a highway boogie!
