Koi pond. Foam lining, fibreglassing & topcoat

[@jobyrneprice5727]

Still enjoy watching you work , we completed our pond two nearly two years ago , everything we did we learnt from watching hours of your videos. Nothing like the size of your jobs , only about eight square metres. Thank you for your clear videos , not tutorials!

Hello there, love your KZbin video. My question is why in the European countries you guys like fiberglass koi pond rather than liner? I don't know why here the united state we don't use fiberglass not much. Anyway about your material you use for the koi pond, does any foam lining work or have to be specific kind? My question next is about fiberglass resin, what kind resin should I used or any fiberglass resin? And my last question is about your topcoat , does it have to be specific kind of topcoat or something else? Please help me out. Thanks
