In the process of stripping my body i found on the back quarter before the wheel well a bunch of little tack weld and about 1/16 of an inch of bondo over them. Should I grind them down a little bit and them re bondo? Or can is there a way for me to knock them out?

They could be spot welds from a dent puller. Posts are spot welded to the dent, and the puller clamps to them to pull the dent out. Then the posts are ground off and the low sections filled. Or an old fashioned one that uses holes was used, and then the holes are welded up. 1/16" of filler is fine, so it sounds like the repair was done decently. Does it look like the area was previously damaged?

Is there a better way to fix this because I'm finding it ina couple of other spots as well. I was really not looking to ra-bondo like this. Can i grind down some of the higher spots, or maybe even with a file?

I am no body expert (do my own work and thats about it) and of course cant see your panel, but if the panel was restored to the point of only needing 1/16" of filler, I wouldnt worry about it. I have seen panels that were just slammed full of filler without even trying to pull the dent, and that is where problems occur. Of course you can grind down high spots if you want, but will it lessen the amount of filler needed or increase it?

well it lookis like some one started to grind down the high spots and then just stopped. Before i started stripping the car i thought the quater was all bondo but the whole section was just convered with it. I'm going to try and grind them down a little bit but what do you suggest using like a really rough sandpaper or a light grinding pad? Or should i use both?

if it is real thin bondo i would use rough sand paper. like 60-80 grit. will do the least ammount of damage to the metal. sand blasting also works well if you have access to one of those.

Well this is whats been going on. After i stripped the car I founf little tack welds, I have been using a rotaty sander with a 30 grit wheel. Pressing lightly I worked most of the little high spots down. Am i doing this the right way? I have been using the low spots as a guide. Making sure not to let the sander sit for to long and get any hot spots. Then I would use a file to work them down by hand and a rough sandpaper for some finishing. I've been working on little sections at a time to make sure the lines are correct. Let me know if I'm off the wall for doing it this way. It seems to be working well…
