    A good GRP guy will redo with new gelcoat, and you will be amazed. Machine sanded back, new gel applied, probably by roller, then sanded, buffed and polished.

      I have some spider web cracking here and there. I'm going to try Capt Tolleys. It's supposed to be good for that kind of repair. I have no first hand experience yet.

          I've tried this stuff and found it to be so-so. I would suggest that it's best used in inconspicuous areas, and certainly not on an open shiny panel.

          The old story, if something looks too good to be true...................etc.

              Spider web cracking can be the result of primarily a couple of things. One is obvious, a mild collision with something or overstressing. Another is excessive force used when pulling the part from the mold. Both normally involve at the very least the fiberglass mat laid up against the gelcoat. Sometimes it goes deeper. The boss used to have us sand and buff, they always came back. Then he had us grind away the gelcoat and spray on new gelcoat, sand and buff, the cracks eventually came back. Finally we took it as far into the lamination as necessary to get to an undisturbed laminate layer. Repair the lamination, gelcoat, sand and polish, cracks never came back. Just a little history of lessons learned.

                Greg you are on the money, for slight cracks I Dremel them out and fill with bits of glass and resin mixed with cab. then sand flat a bid down and overlay with minimum of 2 layers of Vail --- very thin fiberglass mat. This would work on dashes that are cracking from the heat than the cam be finished with lighter colored Gel Coat, one thing with cracks going to hardware location, pull the hardware since in most cases that is where it started.
