Body work question for those 'sperienced.

No, have a welder, know how (at least basically), but welder in storage about 300 miles away. Stuck right now. Just looking for things that I "can" do right now, instead of sitting on my butt all winter, watching TV, and thinking about doing it.

In my experience bondo will eventually 'pop' from a filled hole without extra support. If you can get to the underside of the hole, put some fiberglass cloth there and then bondo on top. Another approach (so you're only working on the top side of the panel) is to sink the area around the hole with a hammer, then lay one or two layers of fiberglass, then bondo over the whole thing.

Is it possible to fill the holes with the Eastwoods body solder?

Do it right
Find somebody close with a mini mig and weld it,you will be glad you did.

Welding creates rust Use some body epoxy & glue plugs of metal either in or over them

There's a guy from Joisey that is a WIZARD at and rattle-can jobs ... he goes through SO MUCH "mud" ... I hear he buys it in 55 gallon drums ....

I have cleaned the back and used epoxy to attach a thin piece of sheet metal behind the hole then bondo on the front, also I have "sunk" the hole and used a little bit of fiberglass and epoxy to fill it. Sand it smooth and finish. Both seem to hold up fine. Agree bondo alone won't hold up.

Thanks for the advice, all, think I may "try" the bondo thing out on a trial piece of metal first. If I don't like the results, since I am a novice at the whole bondo/fill thing, I'll try to find someone around with a MIG who is willing to attempt it.

Welding is best and you've asked for opinions and got them...Mine would be to use "all-metal" brand filler if you have to go that route...It's not going to pop from the heat... Only advice would be to countersink the hole{which could be seen from the backside depending on the location}...Ballpeen hammer and a socket on the backside would work to do the job.. You'd need to feather the filler out not just fill the hole and sand it flat leaving a distinct line between the metal and filler..

I agree with everyone, do what's right,not what's easy. You might be able to get a cheap flux core welder at Harbor Freight.With 25% off coupon it might be around $50 lol! But if you still can not get a welder,use panel bonding adhesive. Many brands on the market like 3M,SEM,Norton,Fusor,Dominion Seal, Wurth,etc.

It works best on ground clean metal.

Maybe use a tiger hair type of filler first then finish with a little bondo.

If you fill holes with bondo, the bondo will later soak up moisture and crack through, making it look worse than drilled holes. Bondo is meant to go between metal and layers of paint.

I'll also vote you should weld, or leave them alone.
