Hi Sayed,
Is that the only bay area on your coach that is rusted that bad? If it is as bad as the pics indicate I would remove everything from the wall. Use a wire brush on an angle grinder to remove all rust AND paint. I would wipe it down several times with CLEAN cloth shop rags and lacquer thinner to remove any oil residue etc. I believe the por 15 metal prep would be a good idea in this application as well prior to applying the por 15 coating. Be sure your work area is well ventilated.

Fortunately, this is the only bay that is like that! As near as I can tell, the previous owner kept several containers of fluids including engine coolant that could have caused this. There is also a drainage hole on the floor of the bay about an inch or so in diameter that water could have splashed while traveling. Shouldn't there be a cover for it?

I will take all the "stuff" off the wall including the decals. Do as you suggested. I'm going to do it in two steps. First, do the floor, the back wall and wall towards the front of the coach. Then I'll tackle the wall where everything is mounted and lay them down on the floor of the bay. I'll try not to disconnect any of the power and air connections. From what I have read about POR 15, it is messy to work with. It will be a good learning experience, to say the least!

Thanks for chiming in!
