Picked up the cedar siding on Thursday and used an clear oil sealer on the front and back of each piece. It takes long to soak into the wood than the lacquerer did on the rafters.
The nails for cedar siding were a big issue. I found an instruction guide online and they spec'd 6D, 2" nails with textured heads. They needed to be Stainless steel or hot galvanized. I drove an hour to get these nails because they are not carried in a local store. On Saturday, the first nail drove in where the instructions indicated broke the tongue off .... even AFTER drilling a small pilot hole. I can go on and on, but it took five trips to various stores to finally settle on 2", 16 gauge, stainless steel nails I could use with a nailing gun. No more problems.
On the front of the trailer, where wind and rain can easily penetrate the exterior siding while in transit, I decide to cover the wall sheathing with Grace Watersheild and created a rain sheding wall with 1/4" furrings trips applied over the Grace Watershield. The cedar siding was nailed to the furring strips on the tongue of the T&G cedar boards.
The window was installed as usual and is undoubtedly watertight.
To ensure the siding is securely attached, I am going to use screws on the corners. I found SS screws at home depot: Simpson Strong-Tie, 1-5/8 in. Lobed Flat-Head Stainless Steel Multi-Purpose Wood Screw. The smaller the gage number the smaller the screw diameter (opposite of nails and wire diameter, sheesh).
