Thank you for the great video. I really appreciate it. I've got a 22 year old bass boat that has spider cracks. At least now I know how to fix them. A lot of guys just let them go. Looks like a good project for this old retired guy to take on. Thanks again.
A thing to consider is that spider cracks just don't appear for no reason. There are three reasons for spider cracks; 1. Impact - in which case all the gelcoat needs to be ground off to expose the damaged laminate. 2. The gelcoat has been wrongly applied too thick. Gelcoat doesn't like to flex so the thicker it is, the less flex it has. Also, as it ages it become harder and stiffer and the cracks will appear. 3. The laminate is too thin and flexing too much for the gelcoat. The laminate spec is, therefore, not enough. It also could be a combination of 2 & 3. Cheers
gelcoat starts to crack just like this after 20ish years. ive seen it on 2 machines my familys owned since new. you wont convince me it was anything other than the sun and elements on these and so imo your 3 ways are not the only 3 ways possible. if the machine is a year old with cracks. sure.
@@tylerhoward2703 What happens is that over the years, styrene is leached out of the resin/gelcoat and it becomes more and more brittle. And, which exacerbates those three deficiencies I listed. Cheers
Oh boy, I wouldn't want to be the one fixing that...I think you'd probably sand back and feather a wider area around the crack down through the flake, re-apply the glitter flake/resin layer(s) and then clear resin on top, but I've not had to do that before myself.
People say it’s not waterproof but you spray gel coat over top of it and dynaglass is much stronger but a little more expensive but you get the money back by how much less time you have to sand on it vs gel coat with silica on it
This was the perfect video for someone who already has a basic understanding of paint and body work. He kept it quick and simple and left out all the unnecessary fillers.

Wont it crack again if you do not strengthen the foundation/polyester?
Lovely shot of the M2 bridge by Cuxton 😉😃
Looks great! 🎉
What is PVA
hi guys how is the boat coming along when will we see the new videos of her progress ?
Thanks for the video. Quick Question: But what if the cracked gelcoat’s clear (and glitter flakes underneath)??🤔

what about fumed silica to mix with gelcoat
You can also use dynaglass that has resin mixed with it
People say it’s not waterproof but you spray gel coat over top of it and dynaglass is much stronger but a little more expensive but you get the money back by how much less time you have to sand on it vs gel coat with silica on it
I have some experiments planned with different patching mixtures for later in the year, I'll add that to the list!
Fine and dandy when it's not a textured surface
I am so happy the music was so loud, otherwise I would have got something from this.

I guess one shipwrights properly is another's omfg
Video is far too short no explanation
Too fast of a video and not explaining properly
Video is useless
because you dont understand it... its not a "for beginners" tutorial
