Is anybody familiar with "gluing" on patch panels?

You will have to weld the panel at the lap joints, you can glue the pinch weld areas with no problems. What happens when gluing lap joints is the line will become visable over time no matter how much filler is used to cover your lap joint it will become visable, we ran into this at the shop about 7or8yrs. ago when replacing quarter panels we glued them complete an about 2 months later one came back an the seam was visable on the sail panel no loss of adhesion or anything like that and you really could`nt feel it but you could see it.
