Does anyone know how to paint the drop ceiling grids? What type of paint can you use? Can you use the same paint for the tiles as well?

Id get some spray paint for the grids, and as for the tiles or panels, id replace them with new ones just colored like you want from the factory. If you don't want to do that, id rent you a spayer and spray the hole thing grid and tiles. As for a paint , maybe a semi gloss laytex

I was told to use RUSTOLEUM for the grids, would a semi-gloss latex adhere to the metal of the grids?
