Bicycle Mechanics - Fender Stay End Caps

I keep losing the little plastic caps of the ends of my fender stays. Does anyone know where i can buy a small bag of them or have a good substitute? I sliced my leg open pretty good on one of the exposed ends the other day so I'm starting to think the end caps are not optional. My LBS said they have a really hard time getting just the caps to keep in their shop.

I'm considering trying some heat shrink tubing but I thought I'd ask here first to see if someone has a better idea.

My first thought was heat shrink tubing. An alternative is short sections of small diameter plastic tubing. Hobby shops should have it as it's used a fuel line for gas powered model planes.

What I've done is cut off the excess stay length after fitting and aligning the fenders. I cut the stays just past flush with the clamps so there is almost nothing sticking out to get cut on. File the ends smooth to remove the cutting burr.

Round off those stays with a dremel or file and cut the stays down as short as needed. Those end caps always come off and the sharp ends are a hazard to skin and clothing.

Wrap with old intertube? You can use that stuff for anything. It's like duck tape for bikes.

Just chop the stays. I lost all my endcaps, too.

Presta valve caps and Elmer's glue

Another vote for chopping the stays down, and then filing the ends. It takes some time, you may have up to 8 of them to do, but it's worth it. If you chop them down real close to the bolts then you won't even need the end-caps. If you chop them down with a little bit spare, then put the caps on and they shouldn't get knocked off again because they are more out of the way.
