: Hi Ross: I had some hatch marks left on my Chessapeake hatches after I've
: left it in the sun for some hours a few times post paddling. I have never

The space below my hatch straps and bungies also show fairly permanent color differences, but like you say they are under the straps and bungies. I don't see this as a problem, it is just part of the natural patina an older boat will acquire over the years. It goes well with the scratches and scuff marks.
