Ok, I have read the threads on removing the manufacturers seal stuff. So I duly put a little totthpaste inside and outside all over the lenses. Left it then rinsed it off, however I'm really struggling to get rid of the smears from the toothpaste and also am worried that the mask will still fog up as it does if I wear it. Leaving for madagascar tomorrow.....!! Any tips appreciated! Also any tips for naming a scubapro everflex, and also my mask and snorkel as a permanent marker doesn't seem to work on them.
