DIY quarter skins

The glue is used on a lot of new cars. I dont think I would use it one a 1/4 skin. Im not sure how it will hold up against body flex when you start making some power.

I would weld the seam, grind it down and cover it with lead, then use a little plastic over that. On the back I cover ther weld with a bit of seam sealer then the heavy factory type under coating.
