Daggerboard repair

ask time intheboat, heres what he said on another thread (dinghy development, page 2, gelcoat repair):

I've just spent some quality time with my boat and here's some top tips of things I wish had done.

-   tape up outside the area being repaired
-  don't put too much on - it's a wotsit to sand off. better to build up.
-  try to get it as true as poss before you sand
-  if it goes in awkward places (centerboard case) work out first how you are going to sand it down.
-  get a white boat

Things I got right - eventually
- use epoxy not gelcoat for chips on the trailing edge of the board
- 400 is the lowest starting point 1200 is good to get that final smooth point
- lots of water with W&D - always use a block

What's the problem with gelcoat? If it's for coating purposes that's exactly what the board is coated with from new.

Now that you've got the tip glued on, get some dawn grey gelcoat, sand the glueline so that there is a feelable dip, apply gelcoat wet & dry flat and the repair will be invisible. There is not really any need to paint.

If your fussy you can probably put your marine filler (Adequate but perhaps untidy) right with this method.

no idea im just repeating what ive heard.
