Rustoleum paint wrinkling is a complex phenomenon. There’re some reasons for this phenomenon. First, the temperature plays a key role. In the summer, when it’s hot and humidity is high, the sheen of the paint may change. In the winter, cold and dry weather will cause paint to wrinkle. Secondly, the sun must be responsible for the change of the sheen of the paint. So if you don’t want to see your painted surface wrinkling, you can use Rustoleum’s Showroom Shine Paint, which is specially designed to reduce the possibility of the paint wrinkling. It’s made of special chemicals to help the paint retain its sheen, so it’s more resistant to the influence of the environment. It’s useful in preventing the paint surface from wrinkling.
