OK, this isn't all I got done today, but it shows that I am listening.
First I had a hole in the cowl.

That patch to the right isn't mine, it came with the truck.
So I used my new metal snips to fit a patch, first scribing the piece to be cut and then test fitting. I filed the hole until it fit.

Then I welded it in place and used a die grinder with a cutting wheel to take off the excess weld.

Yes, I still need to work some more on that old patch. It is right over a support brace and in a very difficult spot. I tried to hammer and dolly it up and got some of it to come up, but not enough. Back to my patch
Then I grabbed a flap disc and here is what I have.

I then took a hammer and dolly and started practicing on raising it where it was low and lowering where it was high, and it is pretty close.
Oh, no pinholes. I used a light on the outside with me on the inside looking, and then vice versa. It is solid.
