I found and bought a stick when I first got my Nash. Before starting on the car, I got some tips from an old friend and did ok welding thick material. But when I got to sheetmetal, I tended to blow holes in everything. So I sold it and bought a mig welder and it is a world of difference. It is really easy to use and make a decent weld without warping the sheetmetal. I just finished making a hood scoop for my Spirit out of sheetmetal and did not warp anything. There is no way that would have happened with the stick welder. As far as the holes go, if you do not weld them shut, which I have already done on my Nash, then they will be back because the bondo will work its way loose and fall out. To me, it will save you a lot of time and headaches in the future if you take the time to fill them right now.
