1 - I would clean the metal to a shiny steel before welding- it will make a big difference.
2 the plastic protector on some stainless metal is very difficult to remove if it is old. I have tried getting it warm/hot, paint thinner, and a scotchbright abrasive. They can all work, but it depends on how much time you have and what final finish you want on the material.
3 yes the bronze filler metals are a more sluggish puddle.
Hope this helps!

Jim Howse Spray and pulsed spray really are great processes and sometimes they are not understood well. I hope the videos help and when you get that new machine reach out to me if you need any help with it.
Thanks ,
