Purchased a GC3, in good condition physically, but was not set. I an getting quotes on setting it up with new cloth. I am wondering how I tell if I need new rubber - since its not setup. Most of the mechanics, locally, say I need to decide if I want to rubber before they put new cloth on it. the cost isn't huge, but not something I want to do just because. Table has been in storage for 12 years, apart. Thanks for any advice.
