crack in hull anyone ever use this?

[fmx_Bud]

I've got a crack on a 92 sj I just picked up. It is prob 10 inches long and is on the top of the left gunale and runs down the back. I want to know if anyone has used this stuff with and success. I have zero experience with fiberglass repair.

ive used it for gouges in my hull never cracks but its pretty good stuff

Thats really just a filler, if the crack moves around at all it will just open up again, fiber glass and epoxy ties it back together , prepping it is key sand a valley were the crack is and glass it if it moves at all or it will keep getting bigger.

Ya, you need to use epoxy resin with fiberglass matting/cloth on that ski. Its top deck is made of metton and nothing else will stick.

I always thought it was funny that marine-tex claims "hardens like steel".... "sands like wood"
WTF?!?! Total oxymoron.
Ya it sands like wood alright, but is not hard as steel. That stuff is for a emergency repair at the lake or soemthing. Its pure crap!

Before you go grinding away on your hull, first determine if its an actual crack in the hull or just a crack in the gel coat. From your description of the location its in a very unlikely place for a hull crack. A gel coat crack is a more common supect and is no big deal. Marine Tex is a cosmetic filler and will not work if you have an actual hull crack. Post a pic if you can

227, he's talking about a square nose Superjet. There is no gel coat at all on a square nose.
The bottom deck is SMC with paint and the top deck is made out of Metton, which is a engineering plastic thats formed in a mold and its also painted too.

I have had great luck with marine-tex
works great on the outside of the hull
Good stuff!

 

[tor*p*do]

oh, and it is a 2 part epoxy based material, so it works on skis

 

[restosud]

good stuff but not intended for your situation.
assuming you have a real crack,only fiberglass and epoxy for you.

heres the pic. its a 92 SN, so whatever the hull is made of, I don't know. So I'm going to stop drill the crack then use......... to fix it. damn it its a bmp file. how do i change it to jpeg?

Gotcha- My bad. I should have caught that when he said 92 SJ.

open it in windows paint then "modify the pic"(by adding a random tiny black dot somewhere on it so that its a slightly diff pic) then click save as. When you are typing a name to save it as..right below that it allows you to save it as a jpeg.

 

[fmx_Bud]

thx. the crack is on my other left my bad.

 

[McDog]

Put some footholds in. Problem solved.

 

[tor*p*do]

crack way too big for marinetex, it is only good for surface spider cracks
epoxy and glass is the way to go
foothold time!

Like said above, foot holds and reinforce the tray area.

might want to be ready for a refoam too, thats a decent size crack

 

[fmx_Bud]

I am hoping that I won't need to refoam. The ski has been sitting for about 3-4 years in AZ here where its stupid hot so I'm thinking the foam is going to be dry. it didn't seem like it was super heavy in the tray area.

 

[shawn_NJ]

I would chop that busted area all away and refoam atleast that section. Then lay a few plys of a quality glass cloth over foam if your not going to do holds. That is a pretty damn bad crack, that marine tex isnt going to do S__t for. Where did the hull come from? It almost looks like water got in there and froze causing the crack.
