Hello,
I am replacing the roof on my rv and will have to put tape on the seems where the plywood meets. I understand that I will need to use the primer because of the new wood. Can I use Duct tape to cover the seems where the plywood meets or do I need to use a special type of tape.
2# for my roof flashing can rubber roof be use straight on metal or do I need to use something to prepare it beyond the primer
