The new pans are held in place with aircraft-style Cleco fasteners,which are temporary. Then Rust Busters begins the busy task ofrosette-and bead-welding these pans into place. Rosette welding is aplug-and-fill form of spot-welding.		http://images.mustangmonthly.com/howto/173_0411_pan_23a_s.jpg

Our installed floorpans look like this. For corrosion prevention, weuse self-etching epoxy primer/sealer, then body sealer at all the seams.Underneath, we use a high-quality, bulletproof sound-deadener andundercoat.
