How deep are they? You need to sand the hood anyway, can you sand them out?

Fiberglass "spidering" is near impossible to cover... and still flex without checking the paint. On older machines, once the gel coat on fiberglass cracks, that's pretty much it. An inexpensive alternative is to paint the surface black, as when the checks come back they won't be so noticeable. Come back they will... Adding an flex agent in polyurethane finishes certainly helps.
