Andrew's SN Superjet

I was talking with Blowsion and sense the SN upper hull is not glass they said to use there stuff they offer... Any input on this?

Correct, it is smc, so you can't use polyester resin, the cheap stuff you get at the hardware store, you need epoxy, which I am sure is what blowsion is selling

So the 1708 and 1208 cloth will work aslong as I use epoxy?

Your cloth won't cause issues, it's just epoxy is the only real thing that bonds to smc.

Okay, would it be more beneficial to use Kevlar or carbon fiber? Carbon fiber is probably not sandable for a good out side finish?

I have 0 experience with Kevlar. But to get a smooth finish on carbon, you sand, clean, brush on new epoxy, sand. With finer sand paper, repeat. Carbon works great.

Thank you.

One downfall is gel coat will not bond to epoxy, if that's your plans. You would have to primer first.

 

[Strangfactory]

Gel coat is only on the bottom side of the hull?

Errrrrr....? Good question. I've actually never seen an oem square that has original paint.... Round nose has top and bottom. I thought squares did

 

[tomski]

There is no gelcoat on his ski.

Edit: please stop confusing this guy.

 

[ProSouth]

I thought he was asking if factory skis did. Maybe I got confused, happens a lot. Sniffed a lot of glue

 

[Strangfactory]

Haha, I thought I read somewhere that SN didn't have it. Thanks Tomski.

Do you guys know what's the best temperature range for epoxy to setup?

It depends on the hardener that you choose to go with. There's fast hardeners, medium, and slow. Tom21 has said 70 degrees is a good temp for epoxy to setup in though.

And you don't want to use carbon fiber or kevlar for this application. Fiberglass is the best since it has similar flexing characteristics as what your ski is made out of it. I don't know all the strength specifics on it, but I know a few layers of 1208 or 1708 will make it bombproof. Also, if you don't have much experience glassing, you don't want to start with carbon fiber or kevlar. That's a whole nother world.

So do I need to use twill? Also do I add cabosal to the epoxy when laying the fiber glass or is that just for filling areas?

[Roseand]

No you don't need to use twill..
You just use cabosil for thickening and filling areas.

 

[Strangfactory]

Thank you guys

No problem! At first this stuff is going to be a little confusing. But there are some threads about this stuff on here too, if you use the search button you'll find some stuff on fiberglassing, and go through some of the "my ski and buildups" section too.
Good luck

Newb question that I could quite find the answer two. She. Doing two layers of 1208 bixial glass do I need to let the first layer dry first then sand or can I get the first layer on and wet and add the second?
