went offloading the other day. mud and sand. what night mare next day cleaning the truck off. what do you have that would help the process after the fact. i used purple power on the wheel wells and frame and everything else under the truck. took me a good amount of time. very frustrating process. i am very particular when i comes to dirt. i had the truck treated with ams oil hp a week before i went. good couple of coats of ams oil hp. thank you. dennis
