Unfortunately the instructions are totally incorrect. There are probably hundreds of other videos with the correct instructions. Sorry you got mislead but remember, just because it's on the internet, doesn't mean it's true. Good luck with the redo. Once done right, you should be very happy. Chuck
I did strip it to what I thought was good enough but I guess it wasn't. After putting on 4 coats the correct way after stripping and washing, , I can still see a little bit of swirl marks from the original application. Don't believe anyone will notice it unless they go right up to it and look real hard. Even with that, I am still very pleased. I did the front cap the correct way and it looks perfect. When we get home from FL next spring, I may just strip it down again and start over. It's only on my slide out wall. I'm waiting now for the guy to buff the rest of the RV so I can finish the Zep application on the remainder of the rig.
Here are couple of tips:
Make sure the RV is super clean and all the oxidation is gone.
Apply the Zep with a clean/dry Micro Fiber cloth.
Fold the cloth so as to end up with a 6" X 6" square or there about.
Pour some Zep on the cloth maybe 1/4 cup. You don't want it dripping wet.
Apply the Zep by rubbing back and forth a few times in a couple of directions.
When you feel a little resistance, STOP. Don't try to go over it again. Wait until it dries completely.
Step back and look very closely for any runs. Get them now before they dry.
I believe three coats would be enough. I went with 4. It doesn't take long to apply.
After about 20 minutes apply another coat.
