Getting the beads to go into the tube was a challenge. Without going into a lot of details, I followed the advice of others and used a vibrating engraving tool to keep the beads moving. I put the tip against the hose clamp and tilted the bottle so as to keep a steady flow without dumping so much that it plugged the tube. Have patience, it is doable

When I've had a chance to drive the car I'll report back on my experience of driving with beads installed.
BTW - I found the cheapest source of beads to be a local tire shop that was listed as a Counteract dealer.
