Radiator Repairs

[Ali]

I'm hoping someone here can assist me with helping out a friend that picked up a small radiator leak thanks to a rock been thrown up into the radiator.
I'm happy to pass on some beer money for any assistance. Sure, Silverton Radiators can do the repair for him, but it will cost a small fortune. He is based on the East Rand but willing to travel if needed.
See attached pic on the radiator.
