===Acquiring patch panels===
There are a couple of ways you can acquire a patch panel to weld in. 
#You can buy patch panels. This is not always an option if the vehicle you are working on isn't a popular model.
#You can fabricate your own patch panel.

===Procedure===
#Make sure the panel/skin is in reasonable shape before you work on it; dents and formal repairs in the good part of the panel will distort the shape when the patch shape is cut out.
#Give yourself plenty of room with the patch; check if you can get behind the weld area.
#Cut the patch and then the panel, make sure both edges "match" together
#Clamp the panels and spot weld the panel in. Don't get it too hot.
#If possible, use TIG or gas, both produce a "soft" welds; MIG will work.
#Hammer weld the welds when hot (red). This stretches the weld; remember -- welding steel contracts the weld area.
#After spot welding, hammer and dolly the area to get it straight. Light off dolly work is best.
#Continue to weld in 3/4 length steps, don't get the area too HOT!
#Continue to hammer and dolly.
#Metal finish the area, use paint or large marker over area, block sand to find high/low spots. Hammer and dolly until there's little left.
#For best results use a shrinking disk on the imperfections, or use [[bondo]].
