OK...so I have a couple holes that I would like to fill in a metal CP. The problem is that the new holes I want to drill will partly fall in to the current "hole".
What material should I use to patch the hole? Should I try to drill my new holes first or could I patch...let dry...then drill new holes?

There is perhaps some way to "patch" metal. But I don't know of any. If I where in your position, I would simply start over with a new metal CP. You can try bondo but its not really suited to fill holes that will be taking a beating.
Only other thing i can think of is to weld it. But that's excessive.

If it were me . I would use a piece of sheet metal under the CP
solder it in, or jb weld.
fill with bondo. let it harden. and drill. I find bondo is plenty stong.
I have never had luck drilling into a hole. drill bit jumps into the other hole and makes a ugly mess.
unless you plan on running a car over your CP . I think Bondo is stong enough

There are a number of ways to patch metal, so normally there is no need to "start again with a new panel". :dizzy:
Standard technique (as seen in the Restoration section of the wiki (http://wiki.arcadecontrols.com/wiki/Restoration)) shown here:

BUT, having the hole overlap is the determining issue. As daywane point out, bits jump when trying to drill into a hole. Now, if you don't mind the extra panel depth, just patch as per Tony's tutorial above and drill new ... likely not a big deal for your project.

How big of a hole is it?
If it's a button hole and it only overlaps by 1/2 inch or so you should be fine.
Something you could do is take a patch of metal and have it braized in to cover the old hole, then use bondo to flush it up. You'll never know it was there.

I had the exact same issue with holes in metal. I cut a 1x2" rectangle when what I really needed was a 1/2" diameter hole, don't ask me how I screwed that up. Anyways, I took a piece of wood and clamped it underneath the hole and then took some bondo and filled in the spot so that it filled the area plus a little extra. After it dried I sanded it down, but it turned out that my spreading job wasn't that great and the other side (where the wood was clamped) turned out to have a smoother finish. So I flipped it over, sanded it smooth and then using the drill press, I made my 1/2" hole right into the new patch. I haven't had a single problem with the patch being weak. The key is to making the existing hole kind of rough. Take a metal file and rough up all the edges, the bondo will stick better that way. And when you're using the bondo, do it in a WELL ventilated area. I did it outside and it still stunk horribly. Good luck!

What I did on my centipede (http://forum.arcadecontrols.com/index.php?topic=21390.0) was get another piece of metal to go over the whole top surface and it had a bend at the top to wrap around the edge.
I cut all my new holes in this and didn't concern myself with the crap underneath. I got the new piece of metal welded to the original panel and bondo'd the bottom edge so that the curve was smooth.
