I washed the lamp, then spray painted it glossy white. Once that had dried, I mixed black acrylic paint with a silver leaf glaze and brushed it on the pineapple and a few other areas of the lamp. I immediately wiped it down with a rag, leaving the crevices darker to highlight the wonderful detail of the lamp.
I'm happy with the results. I have some ideas for the shade, but I'll save that for another time.
