glassing question

[SkiDiggity]

Well i just installed my footholds and got them all glassed in on my 94 sn. I used a polyester resin though and i was told it may delaminate.

Is that all i have to worry about? What do you think the time frame is before it starts delaminating? And before i turf it should i grind everything off and redo it with epoxy resin?

Thanks,
Shane

Why waste money on turf when you know it will break?

Before I knew any better I patched a hull with poly resin and glass. It held for about a year before it let go. But, ithe patch didn't see near the amount of stress foothold will experience. When the patch let go it was evident that the only thing holding it in was a pure mechanical bond. I would expect your footholds to last no more than onecseason before they start to leak water into the hold and/or let go altogether.

Not what i wanted to hear well it looks like i wasted a bunch of time. When did yamaha start using fiberglass hulls? and if i do epoxy will it hold for sure?

Epoxy will stick to SMC, polyester, vinylester, and other epoxy.

 

[SkiDiggity]

so grind it out and redo it then is the only option i have unless i want to redo everything in the future

 

[snowxr]

Yep, do it now, and save yourself the agony later. Lesson learned.

If the top deck of a square is the same as a round nose it is made out of poly resin and that poly resin around your foothols will be fine, its only the bottom deck (SMC) that you HAVE to use epoxy on.

i don't think that it is because when we sanded it down it gave off like wood shavings it was weird.

WRONG. SN tops are plastic. Ridgid injected metton, if I remember correctly. RN tops are fiberglass. Either deck should be repaired with epoxy resin. Poly does not bond well with either. The SMC also need epoxy resin for fiberglass work, but SMC panel adhesive can be used for filling gaps.

thanks for the help guys

wait so jetskis arnt aluminum?

 

[SkiDiggity]

haha funny lol

 

[SkiDiggity]

ok i have a question what about vinyl resin i think is what it is called.

 

[snowxr]

Ok, what's your question about vinylester resin?

 

[SkiDiggity]

i used that on my repair in the front of the boat where i flatland on it and it held so what if i used that that is my question

 

[kiddioo]

Why not use what is reccomended?

 

[SkiDiggity]

well i may be leaving it as it is, but that is what i used to repair my ski so i figure that should work just as well

Vinylester is slightly better than poly, but mosly because it's more flexible. It still doesn't bond nearly as well as epoxy. But I'm sure you asked for advise so you could ignore it, and hear us all say "blah blah blah, I'm a dirty tramp"

I think he was asking about the vinyl resin b/c he already has a supply of it, not to just ignore the advice of others. I would also want to know if I would be able to use a supply of material I already own rather than purchasing new materials.
