I have 2 pieces of wood butted tightly together and I can't seem to remove the visibility of that line. I used bondo and primer but after I sand it down so that both pieces are flat and smooth, that line shows it's ugly head. I'm more worried that it will come through after I paint it. Not really sure what to do about it. If I rub my finger over it, I can still kinda feel it so not sure if this will be a problem when I go to paint or not? It's like I need something that's thinner that could penetrate into the seam better but Primer doesn't seem to be doing it.
The paint won't be anything fancy, I just plan to spray on some premium exterior water based paint but since my arcade cab will be white, I suspect it'll show.

Cut a small vgroove in the seem and use bondo. Make sure you don't just use your hand or fingers on the sandpaper. Take a good flat block and sand smooth. After that I would spray some primer on it and see how it looks.
Worth a shot

This is so true. Your hand will press into the paper causing it to sand a divot into filler material.

Thanks, that's a really good idea. I use a belt sander, orbital sander and a manual block sander depending on what I'm doing. Maybe next time I should just leave a slight gap in between them and fill it.

If you are using some sort of manual block sander, when you put some bondo on and sand it, you may see the seam but if you use s good primer/sealer and a couple good coats sprayed on you shouldn't see it anymore. When I laminate wood together and then sand it I always see a seam but after the primer is on and blocked its all good.

The same here. I always cut a small groove, allows for a little error and takes the jarring line out.

It's already been mentioned here, but use a block sander to prevent divot creation and then a good primer, two passes and it won't be seen anymore.

If you can see it in the primer you can bet real money you will see it in the final paint coats. Remember to use a sanding block and you may need high build primer or even some more bondo/filler depending on the depth of the line.
