My SQMS is having difficulty getting hold of zinc oxide tape through the correct channels. I'm competing in the Marathon des Sables (150 miles across the Sahara in 6 days) in 2 weeks time and after a few training runs with civvy tape on my feet it doesn't seem as strong as the issue stuff. Does anyone out there have a roll or two going spare? I'm raising money for the ABF and I'll chuck a few extra quid their way if anyone's able to help me out. Many thanks.
