Hairline cracks in gelcoat

[Diabalo]

Washed the van roof today and notice some very fine stress cracks in the pod gelcoat in one place about 75mm long and radiating out about 25mm, I not seen any evidence of water ingress but it will it will need fixing. I have looked at a couple of products, Captain Tolleys creeping crack cure and another called MagicEzy. Anyone one used either of these or is there something better to use.

Captain Tolleys worked for me

Having owned and fixed glass fibre boats you might find that Captain Tolley will not fix those cracks as it is designed to utilise capillary action to fix existing water leaks. To do a proper job each surface crack must be 'vee'd' out and coloured gel coat inserted in the groove, then rubbed down and polished.
Hope this helps.
