Brush painting radiators?

Hey r/watercooling. I want to paint my rads to match my Noctua Redux fans. I found Behr Pier grey and Le Luxe swatches that are perfect or near perfect matches. Unfortunately I don't have access to a spray gun to aerosolize these paints. Is brushing the radiators feasible? The rads will be pretty visible since they're going into a O11D-XL.
