It should not matter the paint you use as far as sticking to the metal casement. You should use a good primer made for metal but the key here is to be sure the surface is clean and try to find a product called WilBond. My spelling may be off, this product will "soften" the current coating allowing for a good bond between it and the primer. I used to work for a painter and he swore by it whenever we had to paint metal cabinets and such. |
