you should be able to fill holes that small with short tacks no problem.
I'd feel a lot better if I did close up the holes but every time I try to tack it the thing blows bigger holes. I still freely admit my skill sucks.
Heat up too high? Remember to tack halfway on another tack, don't shoot directly over the hole you're trying to fill.
I'm using a little 110v Lincoln unit, it only uses A,B,C,D,E heat settings and then 1-10 wire speed. Iirc, I've got it set on "A" with the speed around 4 which is a little slow but I read somewhere that higher speed increases heat. Thinking about it, I probably do hit it right on top of the hole (small ones).
yeah you kinda want to overlay your tacks, let it cool for a second or two and repeat. If you have some sheet metal laying around I would practice butting a couple pieces together with a 1/16" or so gap between the pieces.

If it's blowing through that easy, it may have corrosion on the inside and be extra thin. Nothing you can do about that, but I wouldn't trust the bondo. Something's you can aim the gun almost horizontal so the wire doesnt poke down into the hole as it feeds. Then you can rotate the tip down just enough to get it to zap the hole closed. It all happens in a 1/2 second so kinda tricky but can work.
Can also tack around the hole a bit so the material around the hole is thicker and then zap the hole closed. More grinding after, but can do the job.

.023 wire is where it’s at too. .030 works but its hard to get it to stick without burning through or warping it.
I'm close, using .025
Probably good enough!
Just to be clear... I wasn’t saying use the dynaglass for strength... I like to use is as a sealer over welds because of its water resistantance. If the metal is thin it needs to be welded up or chopped out bigger to be thick enough to weld. Sad but true.
The metal seems healthy, I think it's more poor technique.
No rush is there!? Skunked and bp71k5 got it right.
That is the way to fill small thin holes in body panels.
But... if you have a tube inside the frame. “I think that you do? “ I would call it good. JMO don’t get mad at me guys!
Yeah, I made some 6" dowels out of tubing and stuck one inside each post.
Knock on wood no real rust. It does have some surface scale under the gasket but I wire wheeled it off and will be priming it.

No worries, I just mentioned it’s better to seal up the hole with metal so corrosion doesn’t get under the paint from the inside.

Been a while since I've been on, but glad to see you're still at it with the progress. Wish I could say the same. Your truck is looking good
Not a lot to report but I did mess with it for a couple of hours yesterday. I threw some bondo on the B pillar patches and decided to mock up the Diy4x sliders. What you see just has bolts stuck in the mounts, they're not permanently bolted on yet since I'll be taking them back off to paint the truck.
Looking good!
Yay progress
