Yes, very nice work. The one tool you may want to consider adding to your collection is a spot welder. It works so nice in the wheel wells and trunk drops, returns as you call them, as well as many other areas with the complete tooling kit. This is the inside tongs for wheel house flanges. No grinding of a plug weld to clean up.
Once I have the panel fitted, I mark and remove the edp and any other paint where I want the welds.
