Just FYI if anybody else is considering using JB Weld for this type of thing:

JB Weld is a b*tch to get it to stay put when trying to use it to fill these holes. One of the things I was trying to avoid by not welding up the roof holes was taking out the head liner, since I've heard that the headliner VERY often gets damaged or doesn't go back in correctly. So I couldn't put any kind of tape on the back side of the hole and consequently the JB Weld is almost a liquid and so just runs down the hole unless you let it set up for 30 minutes or so before you start spreading it.

I've used another steel impregnated epoxy called Devcon Plastic Steel Putty for bedding rifles and various other repairs around the house and it's TOUGH. It's a lot easier to work with for something like patching a 1/4" hole, so I'm going to try it for the roof holes (under a coat of Line-X) and for the flare holes (under a coat of auto paint). Whether it sucks or seems to work okay, I'll report back.
