Old enough to know better
I had to replace the CV boot on the drivers side driveshaft (the inner one) as it was well knackered.

Rather than take the 'shaft off and struggle without a vice or the right tools the guy in the motor factors recommended a kit that many of his mobile mechanic customers use. It turned out to be really quick and easy and I recommend it over taking the shaft off (unless the shaft requires inspection).

The kit contains the rubber boot, glue & metal ties, latex gloves, a knife, a sashet of grease and another of some hand cleaner.
Also required are a jack and axle stands, a pair of pliers, some kitchen towel (or clean rag) and protective eyewear.
Under the car. The old boot came off, looks like the metal ties might of contributed to the split. Then I cleaned up the old grease which had also spayed out of the split.

Out from under the car to clean up my hands to handle the new boot (as grease and water impair the glues ability). Measured the old against the new to decide where it needed trimming (there is a guide on the instructions but I found it to be dubious). I Left a lip on the trimmed bit to aid securing inplace. I put masking tape on the joins so they would remain clean having put it round the shaft.

Back under the car and fitted the boot and began gluing (with the gloves & eyewear!). The glue took 45 sec to dry and It should be done in 2cm stages.
I decided to leave it a bit longer to set and had a coffee.

Finally i squirted in the grease and used electric ties to finish as I suspected the metal ties of causing the split initially.

Whole thing completed in under an hour and I didn't even take the wheel off.
