Gelcoat pigment

[Headhunter]

I have a black hull and wish to repair a chipped area on the keel caused by the roller coaster trailer swinging arm on launch & recovery. I have adjusted the trailer to prevent re-occourance.

Where can I source black pigment for the gelcoat, should I use an epoxy gelcoat, can this be used with a pigment?

How much pigment is required and does the mix change shade or colour when it has set?

Thanks

John

It sounds as though you need about a teaspoon full, maximum. Look in the yellow pages for a fibreglass laminator near you. You won't see a colour change using black. Do not over colour it, black pigment, in particular, slows curing.

Thanks JW

I have discovered that Humber sell gelcoat repair in "wee" 250ml tins @£14
in any colour that they make ribs in.
So no need to mess about with pigment etc and the colour match should we identical to OEM.
