If I were to do this, I would print my own maps of all the backpacking and hiking trips I've done, and I wouldn't print them on ordinary paper, I'd print them on waterproof paper made especially for maps. Since I don't have larger than a 10x14 inch printing capability, I would take it to Office Depot or any printer, that has large format printers.https://www.graytex.com/waterproof-map-paper.htm
That ^ was just one company, there are several that make waterproof paper for maps, National Geographic, ZapMeta, Igage, ToughPrint, etc.
So if you would like to print your own maps on waterproof paper, here is a resource for you: http://www.landfallnavigation.com/charts.html
Gat, I have to thank you for the Kilz Primer tip. I have wondered for the last two years how I might go about this and skip the whole stripping work.
