Hello guys, I have a customer that wants his cabin prepped for another coat of stain. I have never done it and would love any information you could give. I have a deckster, roof rig, x jet, and downstream J rod setup with two 5 gpm washers one hot and one cold for equipment. I've done a bunch if decks with F18 and oxalic but I don't want to screw this up. Thanks in advance.
