We have all heard the brilliant tip of colouring your float tip with a black marker pen if the light makes the original fluro colour hard to see. The only problem is that you can’t get the stuff off and end up with a float box full of black tipped floats!
Instead, when you want a black tip just slide on a length of black rig tube. It doesn’t affect the floats buoyancy too much and can be removed easily when required.
