Not sure how much cloth you get in that pack

I'd suggest 4oz cloth, 1st _layer_ 2-3" bigger than the crack in each direction, 2nd _layer_ 1" bigger all around that that you can get cloth and resin separately here here

I'm not an expert though and I've never tried to fix a wood laminate

Hi Dan_T, I have plenty of offcuts of 4oz and 6oz 'S' type glass that you are welcome to have for nothing - I normally chuck them out so it would be good to see them being put to good use. PM me your address and I'll send on. In terms of epoxy resin (you will need epoxy not polyester), SP do small 'mini packs' that come with small pumps. That would be my recommendation as measuring out small exact quantities of resin/hardener is a pain. In terms of your pics, the darker patches of wood are defo water ingress. The grey primer pic looks like a typical Dr Ding failure where the repair has not been capped with glass - maybe worth considering capping the whole area.

Hi Mark, what a great offer. I have sent you a PM.

Many thanks,

Dan T
