acid/sandblasting

[ssbn.981]

hey everyone,

i have just started to get into cnc plasma. i have been acid washing to get the mill scale off before i paint. it rusts real fast.
would it be better to sandblast or just prime over the mill scale.
thanks for any help.

If I am just painting a piece I leave the mill scale and prime and paint. I only remove the mill scale when I want a polished finish or use the Steel FX patinas.
