Body work tools?

First off do you have a compressor to run tools properly? But im doing the same thing and here is some things you may or maynot need.

Good air compressor or buy electric versions of tools
Welder
Body saw or cut off tool
Grinder
hammer and dolly set
Dual action sander/random orbit sander either electric or air
set of blocks for block sanding Dura Block has a nice set for like $50
If you plan to sand yourself assorted grits 80-320 grit will need both disc and sheets. This should get you to atleast the primer stage.
Fillers I use Duraglass (short hair fiberglass filler) and Evercoat (light weight filler)
GOOD Grease and Wax remover
Filler spreaders
LOTS of paint sticks

This all should give you a good start. Then buy things as you needed them.
