The terne-coated "gutter caps(???)" for my home have begun to corrode and to start leaking oxides down the side of my house's white exterior. Does anyone have an info about possible refurbishing/repair, or will I have to rip it out and put in something else as one metal roof contractor has recommended.

I have done several searches and have found nothing on this topic.

Is the metal terne-coated steel, or terne-coated *stainless* steel?

If the oxides are rust colored, then it's probably terne-coated steel - not stainless. Terne coated steel requires painting.

ah yes thanks for the reply...you are correct we now believe it is terne-coated steel, not stainless. Are you saying all that will be required is a little elbow grease and re-paint?

If so, what products could you recommend to get the oxide off?

Terne coated steel was the standard metal used on slate roofs for generations - also known as "tin," because part of the coating is tin (the other part was lead - now it's zinc). In any case, the standard paint used for this metal has always been "tinner's red" or "tinner's green" paint. You can paint right over the oxide with these paints. Works like a charm.
