Fiberglass delamination is usually caused by water getting into the fiber, such as a unsealed window cutout. The fiber will wick water through capillary action. The first thing you need to do is find out how the water is getting past the window frame and seal. Once you figured out the how and why now the fix. You will have to remove the window, and dry the area out. If you can garage the unit keep it warm for awhile and check for moisture. You also can use a heat gun and drive the moisture out. You have to be really sure it is dry be for you Begin the repair. You will have to grind out all of the delaminated material, then dry it out again. You will then have to fill the area with glass mat and resin. You will have to sand and level your repair. Prime and repaint. Quite a job if you haven't done it be for and you'll need a lot of spacial tools.
That is the general process for this type of problem.
I would suggest that you find where the water got into the fiberglass, then find a good body shop to do the repair work and paint. After they repair the spot make sure the leak is sealed.
