Hello, I’m painting the external of my house. I’ve followed the advice i found on here to use the white knight rust guard brand. I’ve primed the gutters and all was well. After letting that dry for 3 days I’m applying the white knight rust guard advanced enamel paint but it’s not producing a good result, it’s patchy and streaky. I’m cutting in with a brush and using the uni-pro trade 160 roller that says it’s suitable for oil based paints. Does it just need a second coat or am I doing something wrong?
