Hey guys Quick question: what do you use to write on laminated charts? I tried using Staedtler Lumocolor non-permament fine-tip markers (water soluble) but they seem to smear very easily even without water. I'm wondering if there is something better. Also, how about something for writing on the transparent cover of a chart bag (like this one) when on the water. The Staedtler markers don't work because they're water soluble. I'm assuming the only option would be a grease pencil? Anyone try this? Anyone know where I could purchase a mechanical grease pencil in Vancouver? Thanks in advance for the advice!
