For the 500 series, the Guillow's grey rubber will do just fine. The blue or green rubber in the kits you can just throw in the trash.
You didn't ask but, I"ll give my opinion about which 500 series kits to build and fly. And which ones not to try for flying.
Decent fliers: Guillow Hellcat, Avenger, Focke-Wulf 190, P-40, Bf-109, Hurricane.
Not so good a prospect to make a flier: Spitfire, Stuka, Rufe.
