My theory is if it the stuff is sticking on that good, leave it!Man I am in a dilemma. I have the cuda 75% undercoat free and the pressure washer is dead think a valve burned. Have a friend with a steam jenny he will lend me tomorrow if he can get it to fire up today or should I just get another PW today? Dam I can always use it but hell 600 right now will hurt but I have to get this done so I can un load the truck this week!
