I remember reading somewhere that white quiver tips were easier to see and decided to change over a push in tip and as already suggested, I used PTFE tape.
Cutting the tape at an angle then wrapping the tip as tightly as possible in a spiral pattern.
Obviously it can be a bit fiddly but with one roll of PTFE you have virtually an endless supply of tape and easily removed if you end up making a few attempts.
Probably not necessary but I then lightly covered with an external aerosol varnish spray.
The varnish spray slightly melted/fused the tape, with the finished job looking perfect.
I want to say I saw every knock and twitch on the tip, never missing a bite but that would be far from true!
However, I did feel especially in poor light conditions a white tip can stand out more.
