You can often get cheaper Garden Shades in the sales part of Homebase. Also I found that buying the small tubs of sample Weathershield exterior paint for walls...it worked out much cheaper. Especially if you want to paint your hives different colours. I have pale green, pale blue, cream, and now a splendid pale pink...which someone had mixed but didn't want. All mine are poly hives. And yes I painted the inside of the internal feeder in the Nuc but have not used it as I prefer the top feeders. It is easier to do if you pour the paint in and swirl it around and then tip out the extra. You don't have to open the hive to replenish the syrup.
