Dave, I bonded the windows to the cured epoxy. If you paint first your bond is only as strong as the paint adhesion to the surface. Like always, sand the cured epoxy first and carefully clean it with denatured alcohol right before application of the adhesive sealant. There's no issue with the appearance with not painting first, as the sealant will completely cover the area you can see through the window. It's also important to use spacers to make sure the bed of sealant is thick enough (minimum 3/16").
