Hi , Yes you can almost see things rusting after sand blasting, with the damp in the air ,it should make me get on with it though! I will need to keep the heat down to a minimum when filling the holes on the new bottom blade. Thanks Simply Bearings had quite a few options on the EE5s, i went for the budget ones, but did i seemed to remember they get a 4 Star rating , so cant be bad. Thanks for your recommendation.
