Small cracks in render - best way to fill 'em??

[numpty with a crowbar]

Evening folks,
Got a rendered wall with a few small cracks in it that I'd like to fill in before I paint over it - any suggestions / recommendations on the best stuff to use?? I assume bog standard decorators caulk is no good?? Preferably cheap and something I can get from a shed

Ta muchly

Why don't you use sand and cement? It's cheap and was good enough for your rendered wall.

Very amusing.

I'm sure he's been waiting 11 months for a trolling comedian like you to come along.
