I am starting my journey to get fully informed on maintaining, repairing and sailing my 2 Hobie Island boats. I was hoping fellow pilots could share first hand experience with using structural adhesives and 2 part epoxies. If you could carry 10 oz. of one product on a 5 month trip in the wilds,What would it be ? Your thoughts an links are appreciated |

Hobie kayak hulls are made out of polyethylene. This plastic is very tough but polyethylene is notorious for being extremely difficult to successfully bond with most adhesives. Most such repairs will fail. The closest adhesive I've found which has limited success with polyethylene (depending upon the application) is Loctite Epoxy Plastic Bonder. It's basically epoxy with a bit more flexibility and a plastic chemical bonding agent. JB Weld and other adhesive manufacturers also sell similar versions of it. I would not rely on this very long for a permanent hull repair, but it may serve for a temporary repair in an urgent situation. |

I'd take 100 mile an hour tape and reapply as needed takes up little space is cheap and sticks to anything. used it on long canoe trips with great results if it starts to lift rip it off and replace and go again. Just my thoughts cheers |

Not to mention 5200 takes days to fully cure, although there is a "quick" cure version of it. 3M 5200 Performance Properties: Polyethylene is extremely difficult if not nearly impossible to properly glue. |

Please see my post above. 3M 5200 marine adhesive sealant is one of the best sealants you can buy for marine use, but it does not adhere well to polyethylene. |

I read somewhere of using plastic milk jugs, if plastic milk jugs are still available. Heating the plastic to fill cracks or voids. I'd experiment first on your neighbors. |

I was curious how the milk jug would work. I took a heat gun to one and the plastic became malleable and tacky and from the hazy color to clear. A heat gun may get it to stick but probably not flow like it should, maybe use the heat gun to prep the surfaces but it would probably take a flame to finish the job, and a little prior experimentation. And than this Milk jugs are usually made from high density polyethylene, or HDPE. In the milk jug manufacturing process, HDPE pellets are usually mixed with recycled HDPE flakes. Because HDPE loses its durability after it has been used, only a limited amount of the recycled flakes can be used. So maybe some HDPE pellets which you can get on amazon. |

If you wish to make small repairs to the TI hull, forget about using milk jugs. Purchase the Hobie - Kc Welder Pro With Rod Stock This will work a lot better. Go to here on YouTube to see a tutorial on how to properly use this. I would not recommend it for large hull breaches. |

We have a hole near the mast where the sail retainer clipped on and was ripped out. We have some plastic saved from another hole we created and will use that for a plastic weld to completely fill in the hole. I bought a cheap plastic welder form Harbor Freight some years back and have done this kind of repair on several kayaks using material from the kayak itself and it worked well. I will, however back up both sides of the hole with SS fender washers just to make sure. |
