Frank,

The key issue here is the preparation of the glass, prior to priming or
painting.

I would suggest sanding the whole lid down with no less than 180, and no
more than 240, with an air powered DA orbital sander.
If you do this task by hand, it is  possibile to gouge the dried up
glass, and it will be a big job to cover this with the primer.

Then use a good high fill primer,              (Sherwin williams Ultra
fill is the best)
and then if you choose a marine top-coat, Awlgrip, or Imron should give
you long lasting results.

Be forwarned that these two paints are very toxic, and will damn near
kill you if you don't protect yourself with nothing short of a body bag,
and a fresh air respirated mask.

Very nasty stuff to be inhaling, or to get on your skin, but the best
for finish longevity.

Have Fun,

            ______________
