What is the best way to remove the proud off of the weld ? The weld seems much harder than the panel and I dont want to generate alot of heat or grind through the parent metal

There are many ways, I use a 2" roloc sanding disc on a 90 degree air tool. The sanding discs are available in a number of grits, For welds, I use a coarse one, turning it slow for control...................john

I use a thick cutoff type blade mounted on a mandrel. If you skip around your welds to eliminate heat build up, follow the same pattern with the grinder. I finish up with the Rol-loc like John.

or if you grab new cut off wheels so they are the same diameter you can stack 2 or 3 on your mandrel to give a bigger contact

I tried the wheels and they worked great. This in cojunction with randy fergusons post on the weldng of sheetmetal made a world of difference. I am now attempting the other bodywork. The fender has some previously done bad bodywork and I am attempting to straighten it. I am relatively sure that most of it is stretched but I am not sure of the best way to shrink it. i have some photoes but not sure how to post them. Can anybody recomend a video or book on autobody?

The best way to shrink is by using a shrinking disc. Wray sells them, I sell them, and a few pirates sell them. You can search the web site for lots of information or do a google search to turn up more. Wray has a video that shows the basics of dent repair and using a shrinking disc. It is one of the easiest to use tools ever in my opinion, and will help you learn what is going on with the metal by its predictable results. No fear of over stretching or over shrinking because both are easy to correct. This allows you to get the perfect balance of techniques without becoming a master metal worker.
