Kudos to TinTin for envisioning this thread and for the significant contributions from "lewster," for sharing his significant experience.
My 78 Sovereign
has many leak issues I working through, but my question relates to the proper way to install and apply sealant to an aluminum patch. I have two patches to install, one on the roof to cover the hole left from on old corroded TV antenna, and I want to eliminate the internal battery compartment and replace the old door with a patch.
One application is on the roof. One application is on the front (side). How should the sealants be applied (probably will use Sika products) both on the inside and the outside of the patch?
What would be most helpful to me is understanding the process once the patch is made and ready to install? For example, do you put sealant between the patch and the skin? In the case of the roof, so you use a self leveling caulk on all the rivets and around the edges of the patch? How do you seal up the interior side of the patch, or is that necessary?
Would really appreciate your input.
