Technical Wood roof and body kits

Just wondering are the kits you received from places such as Snyder or Mac are they pretreated or do you need to treat the wood before you install it

 

Got mine from Snyder's. I treated all the pieces my self. But was a great kit all it all fit well. Really stiffened up the old Pk Up (29) Doors fit for the first time since I owned it. The top was not as Henry made it. Mine was held in place with snaps, so it was removable. (Live in St Thomas) Best move I made was getting the kit. Iceman
