    On the grinder, what kind of grinder wheel do you use? Thanks for the videos and keep ’em coming. I need to learn more!!!

      It’s a 36 grit ‘flap disk’.. I’d have to look up the invoice for the brand, but I’m thinking that a quick google search should pull something up for ya ;-)… If not, let me know. Only thing I can think of to note would be to make sure that the arbor size of the wheel fits your grinder..

    Hello I have a 18 foot fiberglass boat (hydrostream v-king) that has six holes in a 1.5 foot square area, the holes are the same size as the one in the video. my problem is if i repair the holes the way you show in the video most of the repairs will be over lapping each other is this ok or should I remove the section of the bottom and replace it ?

    • ~Andy says:

      You should be fine to overlap the repairs. Since it’s such a small area I would probably do the final couple glass layers over the entire area, then fair the repair for gelcoat..

    I can’t do a two-sided repair as you suggest. I’m repairing a sailing dinghy, and the inside is inaccessible – a very narrow space between the hull and cockpit.

    I was all set to buy the laminating resin when I realized I won’t be able to coat the inside with the mold release. In this situation, it seems I must use the pre-waxed resin. Is that correct, or is there an alternative?

      Hey Greg, I think I understand your situation but if you could please email (or post on Facebook) a couple pics of the repair area I’ll be able to give better advice 🙂 Thanks!

    Aloha Andy
    I have to say I have been in the composit industry for 20+ years and your videos are awesome. I know for me the understanding is super clear, but the way you go about explaining things is great for someone to tackle there own repairs and fiberglass project. Thank you for sharing your knowledge it is rare in our industry for people to be open and informative. Great job aloha Mike Storm maui, Hawaii

    Hey Andy – Your vidoes have encouraged me to get into fiberglass and gelcoat repair on my old sail boat that I wouldn’t have tried otherwise. I have also been sharing them with members of our yacht club and on sailing blogs. Really appreciate your great work!
