- Here's how I deal with splits in my boats.
This video shows you how to fix those nasty cracks & splits in your kayak. There's a few different ways to plastic weld, and this is a 'tried & true' method (using basic tools) that has always worked very well for me.

It's not surprising the way boaters these days to pile up on every rock in the river, and " rock spin"

I don’t understand why you felt compelled to make this video. To me, it just represents another example of bad welding information. There are lots of similar videos out there of folks who got themselves a heat gun and some plastic and think they are ready to weld their boat, or worse, teach others how to do it! First, you didn’t drill the ends to keep the crack from propagating when it gets re-stressed. And judging by the weak quality of your weld (I do not believe you have any real fusion at all there) that crack will propagate. People, instead seek out the professional welding videos from folks who do this for a living, not some yahoo in their back yard who think they know how. Techspan is one good resource (as a maker of professional welding equipment - but alas too expensive for most of us!) and there are others but their technique in their video is much better than this and you can tell it’s a quality weld. Finally, do not weld with a large tip heat gun like this. Get yourself a fine tip heat gun to control the spread of heat and if possible a welding tip with a plastic feeder. If you can’t get a feeder tip learn the fan technique with a fine tip. Harbor Freight sells a fine tip plastic welder that’s actually a decent gun for the $ ($90) but unfortunately don’t sell the feeder tips. There are also decent looking welders on Amazon for a little more $ that come with a feeder tips but I can’t vouch for their quality. A feeder tip makes this job 100% easier and more likely to produce a quality weld. Practice on a totaled boat before working on one you care about.
Holy! What a novel. I appreciate the time you've taken to write such a comprehensive comment. Bravo.
I hate to burst your bubble, but the weld is holding up just fine and it worked perfectly, just like it always does.
I did mention in the video that some folks like to drill out the ends of the crack. This isn't anything new. I covered it.
If you had paid attention to the video, you would have noticed that I was using a fine tip attachment on the end of my heat gun.
As for your product suggestions, remind yourself that not everyone lives in the USA. Some of us live in countries that don't produce or manufacture Kayaks. Because of that, we've got really good at repairing them with basic tools to get as much longevity out of them as possible.
Finally, remember that there's more than one way to skin a cat. At no point did I say this was the one and only 'definitive' way to weld a kayak. It's one of many effective ways folks do it.

Ease up mate. He's just showing you what he does. It worked! Still using the boat too.
Man... You should use a vacuum cleaner for that plastic dust rather then just rub it into your environment...🤦🏻♂️
I'm literally showing people how to repair a kayak so it doesn't end up in the trash.
