What's a Good Marker to ID Swim Stuff?

Cattle Brand Another good idea since most liquid marks will wear off over time or could be removed by someone motivated enough. I tried an engraver but it doesn't take very well on most of the stuff because it's soft rubber. I have some metal working equipment and might be able to come up with something. I will build a fire and play this song while I do it... Rollin' Rollin' Rollin, Though those streams are swollin' Keep them doggies rollin', Rawhide! Through rain and wind and weather, Hell bent for leather, Wishing my gal was by my side. All the things I'm missin', Good villtles, love and kissin', Will be waiting at the end of my ride. I'll will have to act quickly before my neighbors call the fire department and they show up and shut me down.
