It's a plastic paint I bought at a hobby store... I have no idea what brand since it was many years ago.
Light sanding and several coats.
Did the vents too, but they're flaking now. :(
Flux core wire, yes.
So far it's run smoothly with everything I've thrown at it... melted a decent size hole in 304SS. :)
So in conclusion, my purchase has worked out just fine.
I'm just using flux... gasless.
Is "porosity" what you meant?
If so, there aren't many pores in the weld since I grind them down they're full and solid.
Welds aren't 50% cold or 50% hot... just right. :) you can follow the heat under the pipe all the way around.
LOT'S OF FUN!
Just as an update... I made my first project today: my WG dump tube!
Found out it wasn't angled right... so I had to cut it apart and re-try... now it looks like crap!
:) I'll take pics later I guess. :)
Greatest grinding wheel ever invented!
Not necessarily the brand... but the wheel.
