And what is that?

Appreciated

This guy has no idea what he's talking about. Irrespective of the actual effectiveness of any of these products, he's just regurgitating "bro science" and using terms and words he's heard but doesn't understand. I have graduate degrees in physics and aerospace engineering and specialize in computational fluid dynamics. I help design and refine the designs of aircraft, boats, automobiles and rockets. This guy couldn't understand the wrapper on a Snickers bar. I choked on my coffee listening to this cartoonish explanation of hydrodynamics.

Yes and yes, Kevin has exhaustively detailed what FX owners need to do to preserve their hulls. Please review his videos.

You bet!

It’ll ride like trash.

RIVA Pro Series Sponsons.

Literally ANY paint shop will be able to answer this.

Neither

Yeah, ceramic coating won't last very long on the hull.

No idea. PPG?

Never heard of it.

@@watercraftjournal who is talking about sea-doo's ?

Yes, and that's why a clear coat with flex additive is the smarter decision.

@@watercraftjournal I would think that even clear w flex would eventually fail if the oem substrate cracked.

Good question. Optimally no. Again, it's nowhere near as fragile as the internet would have you believe; but two coats of clear with flex additive will keep it contained, even if it begins to crack beneath.

@@watercraftjournal Need advice on a upcoming purchase of a pwc. Appreciate input on what would be best. 2017-2021 Kawasaki Ultra 310lx or 2019-2021 Yamaha FX SVHO. Ultra 310LX benifits: SMC fiberglass hull with gellcoat paint (strong and durable) Best hull in waves and chop Reliable engine Comes with Bluetooth audio Most storage (50+ gallons) ________________________________ Ultra 310LX drawbacks: I don't love the looks, but it's OK Manual reverse lever, no brakes Seat may be too wide when standing High fuel consumption Short rear deck _________________________________ Yamaha FX SVHO Benifits: Looks cooler More available to choose from Easier to upgrade Less maintenance of supercharger pully pivot and belts Larger rear deck w option for rec deck Brake and left hand reverse ___________________________________ Yamaha FX SVHO Drawbacks: Nanoxcell 2 hull delamination worries (gatorglide fix good enough ?) Supercharger clutch failure Not as good in the chop and waves

I have personally reached out to ALL THREE OE manufacturers as well as Cigarette Racing and a custom surfboard shaper on this topic. Differing surface tensions are direct causes for hull tracking and cornering instability. -K

@@watercraftjournal I agree but what causes the most surface tension? I summit it is the hull design. Change the shape of the brake alone will cause the craft to change its turning dramatically. We do not have a disagreement except maybe the degree of change caused by coating. I guess it depend on why one is coating the bottom, preservation or racing. My Ski with GatorGlide turns very hard.

Hey Dave, so is the turn consistent or does it give out part of the way thru the turn and you adjust for that?also did you apply this or someone else ?

@@kamax7672 I haven't put Gator Glide on mine yet I know 4 differant folks that have gator on their entire hull and one just did portions like where the bunks sit. they've had it on for almost 2 years now and they're not getting the reaction or negative effects that Kevin talks about, but what Kevin does say makes sense if you go by the physics of the water tension on the hull I don't know I'm not totally sold on it and not totally against it

@@johnwest2396 it does makes sense what he said indeed, but if you ACTUALLY know physics, you should also understand that those effects, while present, will be so minimal, that there will be no way to notice any difference. even if they affect as must as 5%, you would never notice that, but they affect even less actually.

This is why I'm quitting.

@@watercraftjournal cool story, turn off comments if you can't handle it.

100% We'll link your video in the description right now.

You've got me, Cpt. How do I know Steve Dye? -K

Just what Kevin suggested, 1-or-2 coats of automotive clear coat with flex additive.

@@watercraftjournal I assume you'd still want to sand it afterwards to true it if you are aiming at perfection. After it is true you may want to add another final coat also.

That's the first we've heard.

LOL

it doesnt actually prove anything, you will be shocked how little research most manufacturers do. Products are released with extremely dumb design mistakes all the time.

I should have expanded on my comment. A well know offshore boat manufacturer who had a pad bottom boat design used 400 grit sandpaper on the bottom of the race boats...thus the dull look instead of nice shiny gelcoat. No, I wouldn't do that to my Jetski bottom. 😜

Absolutely not, Mark. At all. Flex additive alters the catalyst to keep paint from cracking - like you said on plastic bumpers. It does NOT evaporate, as much as the catalyst evaporates.

I've seen him shoot. I'm safe. -K

Yup

And how would you like me to do that, Chris? What exactly would convince you that the material I presented is true?

Why don't you sponsor him to do that then? lol. I hope you understand how much labor and time will be involved in that test? So yeah, put your money where your mouth is lol
