From bart de cremer of acotec nv on August 14, 2012:
     Use a good putty filler and cover with a solvent-free, polyamine- cured epoxy.

From B. BRYCE of SCOTTISH & SOUTHERN ENERGY PLC on August 27, 2012:
     In addition to the previous defects I would also look out for cracks and fractures. These can sometimes be expected due the brittle nature and low tensile strength of cast iron. Depending on the scale of crack, a cold stitch repair may suffice; otherwise, the whole casting would have to be replaced.

From Brian Chapman of Cadillac Fabrication on June 18, 2012:
     Two of the main issues I have run into with cast iron are voids or craters in the casting and flash left from the casting process. Both make adequate coverage when painting nearly impossible. With the flash, we usually grind with a small grinder to remove it. With voids and cavities, I will fill with a good quality body filler if possible. Sometimes the only answer is many coats of paint to try to fill in the defects.

From Murjan Murjan of Sirte Oil Company on June 18, 2012:
The type of defects that might be found  are porosities.
