What's a good way to fill up holes in a box ?

[warioblast]

Hi,
I want to use an old box for my new looper project. How can I fill up the holes I have previously drilled ?
Cheers,

Bondo auto body filler.

Solder in a patch.

Epoxy in a patch.

Braze in a patch.

Or any one of the last three AND the first.

Ive been using JB Weld - this can be found an at auto parts store. It comes in a tube in white you pinch a piece off, smash it up / together and fill the hole. I ussually place something behind it on the other side of the hole such as a small piece of perf to hold it in the hole better. You wait an hour, sand smooth and redrill or paint over. Great stuff!!

You can put a thin piece of metal over the top so that it covers the old holes, then drill your new ones through both layers.  I've also used jumbo LEDs with jumbo holders to fill in footswitch holes.

Extra LEDs, or amp-style panel lights for those bigger holes!

They don't need to do anything except light up, but it's even cooler if your can make them interactive with your fx signal.

There are plastic 'hole fillers' at well-stocked hardware stores.  I'm not sure what they're really called, but they're located in the trays with all the hex-head screws and oddball hardware.  They come in various sizes and just snap in place.  I used a couple of them on my first box where I drilled the jackholes in a bad spot.  Yes... jackholes.

Yes, the JB Weld thing works pretty darn good.
Sand the whole area flush as possible after filling the hole and then hit with some filling primer and it will blend right in to the enclosure.
Once you throw a coat of paint on it......know one will ever know.....Hmmmmmmmmmmm Ha Ha Ha Ha Ha

plain woodfiller works nice if you let it dry and pain it well.

I use plast-bond - a two part filler like a few others have mentioned, but I like it because it sets up grey - almost the same colour as the aluminium. 

Two things to add:

I like to scratch up around the hole on the inside surface and also around the inner rim of the old hole with an electric engraving tool, then wipe clean with solvent.  Especially if a jack or stomp switch will be later installed in, or partially across the fill (if you know what I mean).  The filler will adhear to the aluminium much better this way and provide a tougher mounting place for those items.  If you decide to isolate a DC or phono jack with this stuff, this scratching and cleaning is very important.

And save your self a whole lotta sanding.  Use clear tape over the outside of the hole.  That way you can see (what will be) the outside of the fill and push the filler right into the edges with a small screwdriver or something and clear any bubbles.  After setup, the tape will probably leave its adheasive on the fill, but a wipe of Shellite or something makes short work.  If the fill has to be flush on the inside, the excess dried filler can be quickly pared away with a sharp chisel.  Even if you trim it right down flush with the aluminium on the inside, the scratches that you put in the inner rim of the hole will hold the fill fast. 

Very fast!  I had to remove a fill once and decided to see if I could just "pop" it out with a punch and hammer.  After a few heavy blows, I gave up and drilled it instead...

I've been using the latest kind of autobody filler. Its not a redish-brown color like the old Bondo but a a babyblue type color. Its way easier to sand than theregular Bondo and accepts paint and clearcoat better. I would say use that. Put some tape (anykind) on the backside of the hole and then fill it with this stuff. You won't be dissapointed.

I've had to use them three times !! 

On a black powdercoated or "matt black" box ... you can't see 'em
