Hopps #9 smells when fresh, but the BreakFree CLP scent is persistent. I've had ROs who were giving me the start commands during IPSC matches whisper "oh I notice you use BreakFree" just before saying "Are you Ready!". And I only use a bit of it in conjunction with other lubes and cleaners.
The smell reminds me of my childhood though when my dad was in the forces and we lived in PMQs. I kinda like it. It's like comfort food!
