Where to buy Power Steering Stop Leak fluid

[joncastle]

My power steering pump is leaking. I know, I know, I should take it to a competent garage and get it investigated/repaired/replaced, but right now, I need to eat. So, where can I buy this sort of stuff? Drawn a blank so far at TVR Autoparts, Little ACE and Speedex. What am I missing?

Lucas 10008 Power Steering Stop Leak
BlueDevil Power Steering Stop Leak
Prestone AS263-6PK Power Steering Fluid with Stop Leak
Bar’s Leaks 1600 Power Steering Repair
Gunk Power Steering Fluid with Stop Leak
NO LEAK 20301 Power Steering Stop Leak

All suggestions welcomed!

TIA
