Thanks for the video, Lamby. I gave it your first thumbs up.
I think we have the same Gerber multi-tool!
A couple of tips:
1. Get someone to hold the camera for you.
2. Put a written description of the steps, parts and tools needed on YouTube. I think you skipped over a few in the video like how and when you removed the cling film; the proper way to trim the boot and how much you took off both ends. One section on each end?
Looks like you're using this Bailcast CVS18 CV Boot Kit:

I couldn't find it on Amazon US, but it is available for (more expensive than the part) shipment on eBay above.
