temporary patching of torn cv boot possilbe?

[omodos]

Okayz hello to all, saw usual signs of gunk in front wheel arch, and one sides gone so probably other will go too , these are the larger outer bellows I am referring too, earliest appointment at at garage is in 16 DAYS time.

Called around couple of places both said same when asked if an issue to drive until repair date 2 weeks away, they said had it been winter and wet would be an issue but driving it now is ok (note it is very dry and dusty out here)

Anyone got any good idea how I can keep the area and splines inside boot dust free till that date? duct tape not sure will hold on boot, maybe wrap it with a good electrical tape instead so can get in between the ridges in the bellow? any tips much appreciated. I know i cant go too mad as the things needs to flex on turning the wheels otherwise I would have got some rubber repair glue and given it a go that way
