Speedgrip it, no welding on the body panel. We tubbed my Envoy without messing up the factory paint at all. Tack on the outer edges where you can't see it, then I would run a good bead of seam sealer. Then throw on some dynamat and call it good. I'd get some of this badass gel stuff that keeps the metal cool around your welds too. Can't remember the name, but you can get it from Eastwood. Cheap for what it does. Good luck!
