I just used it today as a matter of fact, put a roof skin on a Tundra with it. Its made by 3M and is called Panelbond. I don't trust it but it does make for a nice finished result. You can't use it for a butt seam. For this type both metal surfaces have to be ground clean then you apply a fine bead to both bare surfaces and spread it over the bare metal with a spreader if you will. Then you apply another bead on top of the skim layer to actually bond the panels together. Then it must be clamped tightly until dry or about 24 hours to be safe. We have had a couple bed sides come back with cracking of seams though. I will have to let time show me that its as good as they say it is. It has miniscule glass beads in it to keep from squeezing it all out when it is clamped. It does work well as a plastic repair and on fiberglass.
