I'm planning to make my own panniers out of a set of army map bags -- these are small bags, about as large as a small front pannier, with a rigid back.
The hooks I'm planning to use attach to the bag with two screws and nuts. I'll have to drill or punch a hole in the canvas and packing to get them to stay. How can I seal the holes so that the bags will stay fairly water resistant?
(This is a bit of a test question -- will the board cover DIY-style topics like this? It is a real project I have going, though.)
