The stuff you get from Wicks etc, is ok but takes ages if ever to harden.
For small holes or repair you can nick, dig out some of your existing Asphalt from somewhere, microwave in a plastic bowl (takes a while 6 min plus) till its really soft, then pack it back down with a club hammer for the repair.
That's a good tip! Thanks Zirk!
Any point in heating up the cold repair stuff from Wickes etc, would it make it more effective? 
Yea, the stuff Ive used before is -
http://www.wickes.co.uk/Wickes-Instant-Lay-Macadam-Major-Bag/p/220017Its quiet good gear and not expensive either.

All depends how hard / soft the bag is when you come to use it, also how hot / cold the day is. but in a nut shell the hotter the better as it will stick down better, I have also mixed it and microwaved it with the original stuff so as to avoid wastage and help to blend in the repair.

You tend to get a feel for it all once youve played with it for a while, if that makes sense.
Butas said the trick is to let dry hard before driving over it again, theres probably some stuff you can buy where can brush, or let it soak in to harden quicker but Ive never bothered.
