Mountain Lion clean install

[NelsonMiguel]

Hello. I have two different macs, one imac and one mackbook pro, and i want to do a clean install of mountain lion one both.

So my question is: should i download mountain lion from the app store two times, one for each mac, and create differents bootable usb drives

or just once and use the same drive to install it one the two macs?

Thank you.

I just want one bootable thumb drive - use it on all my macs.
