Grp repair below waterline.

[Gazjen]

What's the correct/best way to repair chips in GRP below the water line?

I've been messing about reconfiguring the trailer over the last couple of days and I've noticed a few chips out the hull that I need to repair/get repaired.
Thanks.

I bought one of these kits when I found a few small chips/scratches, kit includes everything you need very easy to do an invisible repair.

For deeper chips this stuff is highly recommended, although I haven't had the need to use it yet.

Plastic padding gel coat repair does it for me

Not that I have any chip of course
