If you do not feel comfortable with a full repair one thing better than just putty would be to sand down to the existing glass and then apply 2 layers of fibreglass encompassing the cracked area and cross your fingers.
To do a full repair you will need to grind through the glass to inspect the foam sandwhich. No way to really back out of that if you get in over your head.
Sand off the paint and take some more photos |

Their are plenty of helpful Henry's here to guide you along.
You asked about videos, use google or...
Windsurf board repair, I saw several.
West Systems are a company that you can actually speak to human who speaks English .
They West make kit versions of epoxy. Their should be some stores locally that will sell , West Marine, and supply glass or carbon, and will offer advise.
It matters not the grade of sandpaper to start, and a electric sander would be my first tool, you only need higher, less grit for the last finish, I would use wet and 220/320 for that and 80 or 100 to start, depends on how much you want to sand, machine better, less work.
Basically this needs covered with a permanent fix in mind, putty is a temp fix anywhere.
Asking ? Will get you tons of replys _________________ K4 fins

Go ahead and do the repair. I had a serious nose crack this summer. I went ahead and got everything I needed to repair it - foam, epoxy, glass fiber, and some tools, after getting pointers here where to buy stuff. Some tried to discourage me, but others were quite helpful. I also tend to be clumsy, and don't work with my hands much (unless you count using a mouse and keyboard).
I spent about $250 getting various supplies and tools, some of which I did not even use in the repair. The repair came out great, the board looks as good as new. I have sailed it 35 times since the repair, and it is still going strong. I added a custom foam nose protector again, though.
When you do the repair, just go slow and don't rush it. Read what you can find, and ask for advice here. It's ok to make mistakes, they can be fixed. To give an example: I wanted to fill a big hole where I had removed broken foam. The PU foam I had bought did not work, so I used epoxy. In my first try, I used way too much, and it melted the foam next to it. The second try, where I used multiple small layers and lots of epoxy filler, worked like a charm.
I did most of the sanding by hand - it's much easier to go too deep with a power sander if you are not used to using them. Get a bunch of assorted sandpaper, and change it often. Don't forget to wear a mask and gloves. The one power tool that I found really useful was a Dremel tool for cutting out the damaged glass fiber sections (about $30 on amazon.com).
For the epoxy, get the West Marine stuff, including a filler and the metering pumps. Those may seem expensive, but make life much easier. You can always practice on some styrofoam blocks from packing material to get a feel how to work with the epoxy and glass fiber material. |

The thing we need to keep in mind is that rgomez lives in India. I'm thinking that finding the right epoxy and fiberglass products might be a bit tougher than here in the US. |

Rgomez,
Search for a fiberglass supply in India. A large boat supply store would probably also have what you need.
You want epoxy, not polyester resin. Polyester resin is not compatible with the foam core of your board. The stuff at the hardware store is no good.
It looks like the Ding-All kit you mentioned doesn't have enough material to do the job. You'll probably need at least a half square meter of fiberglass to do the job right and enough epoxy to soak it. |

I just put a report with pictures about the nose repair I did a few months ago on my blog at http://boardsurfr.blogspot.com/2015/11/the-nose-job.html. It's not meant as a step-by-step guide, there are better sources for that out there (and I have only very limited experience). It's more a story about how a repair of similar or worse damage can be done and lead to a rather good result, even by someone without experience, and even when running into a few problems along the way. |

Thanks for the help guys. Luckily I found a surfboard builder who is willing to repair it. Hopefully I can learn from him for future repairs. |

I think that's good news!
It would be helpful to gain at least some repair knowledge, it's typical damage that occurs often.
