Nee help determining capacitor polarity

[ScienceGuy]

Patrick of Castle Creations recommmended using about 10,000uf of capacitor on the output of a Lambda power supply that we wish to use for small brushless motor testing. I have a couple of 4,700 uf capacitors from Radio Shack that he said would be appropropriate in parallel and need to determine their polarity. From their wrapper I would think that the right end as viewed in the attached picture is the negative but wanted to check with the "experts"

Thanks for your help

Yes. The arrow is pointing to the -ve end. 'Crimped' end is usually +ve too.
