Personally speaking Serge I would not sand them as the sanding leaves tiny scratches that are potential stress fracture points. Use chemical paint remover and thoroughly rinse with mineral spirits before a final washing with soap and water. Heating could also ruin the strength properties of the steel unless one knows exactly what they are doing. My preference would be to have them powdercoated and forget about corrosion for the life of the bird. Doug Rupert Simcoe Ontario
