The enamel paint on my gutters is pretty old, and it’s all faded and powdery. Can I just paint over it with British Paints 4 Seasons?
By all means. Just be sure to give them a thorough sugar soap wash, and a sanding, too. One coat of British Paints PREP 4 in 1 Oil Based, followed by two coats of British Paints 4 Seasons should do the trick nicely.
