The one thing I believe in 100% is to use a polyester high build like slick sand which has zero shrinkage as opposed to a 2K primer which will minimize if not completely stop any ghosting

Thanks for the response and I do agree the more I learn. As stated earlier by someone else, if a small ghost line in this area is my worst issue here, I will consider this more than successful.
When I think about the best way to do this, I believe it would be best to space the backer to allow the metal bond some room to fill and not completely squeeze out. I made a diagram of this below.
Please keep the comments and experience coming, I plan to tackle this within the next week or so and would like to iron out a couple of these details. I think the backer strips will be about 1/3" thick to properly attach the roof panel and provide a lip for the patch. If there are other thoughts please share.
