A Body fenders

What are you trying to do?

Remove the fender?

Remove the headlight bucket section that was welded to the fender and doesn’t need to be removed to remove the fender from the car?

Weld the holes you drilled trying to remove the fender 40 years ago?

I’ve got no idea anymore. You don’t need to remove ANY seam sealer to remove the fender. The seam sealer between the fender and inner fender you can’t get at until the fender is off. It kind of glues the fenders onto the car. But you don’t need to get at it, they just pop off with a little effort.

Even if you’re trying to repair what you messed up, you’ll need to remove the fenders. And you removed the seam sealer from the areas you already drilled, so, what is the need to remove more?
