Grind out the area that is cracked you will want to get it to bare glass about 1" all surrounding the crack. Grind out any loose fiberglass. If the foam looks bad, dig the bad stuff out with a stick or something.

Clean the ground areas with acetone till they are really nice dark green. Use some polyester resin with catalyst and some milled fibers. Mix the resin and hardener (catalyst) according to the directions and add the milled fibers until you get a consistency somewhere between mayo and peanut butter. Cram it in and let it harden.

Once cured, grind out any rough areas or bubbles that have protruded from the repair. you should have a spot that is slightly lower than the surrounding undamaged areas so you can add a filling/fairing compound and shape and sand to uniformity with the rest of the gunnel. Use the search function on the site and search posts on Evercoat and Evercoat tinting agents. Also search Spectrum gel coat. Evercoat makes good filling products that are poly based and compatible with the oem gelcoat product.

Once the filler is faired out its just a matter of color matching. If you are careful you can keep most of this repair under the rubrail.

Ditto. Same way as the first spot.

Ditto again.

If you want I can PM you with my email or phone number if this doesn't seem clear. It is easy in concept but hard to understand in words. I wish sometimes that I was better with them.
