quarter pannel install questions

For you guys that don't think you weld good enough to butt weld why do you think your welds will be better with the overlap? If you are not good welders overlapping won't make you weld any better.

Krabysniper, TIG welding produces more heat that MIG does. It's basicly oxy/acetylene gas welding with an electric arc flame. This is why you do not get any spatter like you mentioned. Just the same as if you are oxy/acetylene gas welding (no spatter). It's not to say that a good TIG welder couldn't control warpage it's just not easier than MIG. Before I purchased my MIG & TIG welders years ago I used a oxy/acetylene welder on all of my panel work. It can be done, it, like other things in life takes practice to achieve good results.
