Is there a good way to fill pits (up to .150" diameter) in an aluminum
casting (a motorcycle chaincase) so that it can be powder coated? The
powder coating process subjects the part to 400 degrees F., so I think
plastic fillers would not stand up.

I imagine gas welding would do it, but I don't know that I could do it.

I think I'll try the aluminum brazing (or maybe it's soldering) rod first.
A number of people on the net have reported success. Thanks.
