You probably will see a slight difference in the weld area. Can you see the difference on any holes where the gas was used? You probably havent affected the strenght of the weld if when ground flat there are no holes or pocked areas.(assuming good penetration) You will probably need a light coat of filler (bondo) any way on the holes so if its just cosmetic, it should matter. WElding sheet metal is tough, if you havent done much before. Two words, Time and Patience, you need plenty of both to weld body metal. Got an old piece of body steel laying about? Say a fender thats junk? Shoot some holes in it and practice. Play with the welder settings. Make your mistakes on the scrap, then when you are proficent, move back to the car. Does your welder have infinite voltage control? Meaning there are no detents on your voltage dial? IF not and you have detents, you could run into problems as you may not have that "perfect" voltage. This is where the practice on the scrap is helpful. (wire speed is USUALLY infinite controlled, if its not, get a new welder :) ) Doc.
