I typically get about 4 days worth of playing before my overgrips (Yonex Supergrap) completely lose their tackiness. Once this happens, I change overgrips, but feel this is a waste of money because other than the loss of tackiness, the overgrips are perfectly fine. Is there something I can do to the overgrip to make it tacky again? (Any products or home remedies) If not, can anyone suggest an overgrip with the same quality as the Yonex but that retains its tackiness longer? Any help would be greatly appreciated.
