body work for a newbie

[Speedy]

can anyone lend a newbie that is familiar with a MIG welder some advice on welding flush patches on his vehicle.

I have a MIG with shielding gas.

im not sure what I need to cut sections out and other tools.

I have been slacking for 2 months on my project and I think its time I started at least doing body work on the spots I can while the tub is still on the frame.
