Cleveland has given their 588 DSG Wedge a rust-like appearance by using a special RTG+ finish inspired by tour players who prefer clubs with a softer feel and reduced glare at address. After three to five rounds, the finish will wear off at the sole and face. Over time it will completely rust over.

The rich mirror chrome finish makes it a popular choice for traditional tastes. The double nickel chrome finish makes it exceptionally soft yet durable.
