I am planning to fix a few bits of rust on the roof of my 4WD.
My question is what to treat that weld with before doing any painting.
I have no problems doing the welds.
Do I just use my pickling gel and a real good clean like on SSteel and a real good clean?
And also what about the inside side of the panel you can't reach to paint?
----------------------------------------------------
the issue with pickling gel is it might cause rusting on bare carbon steel unless it is neutralized completely.
if it is acid based, baking soda, will neutralize it.
