Re: Alternative finishes?

I put of a layer of this down on a scrap of epoxy coated plywood last night. It cured nicely over night. I'll dip it in water and see what delaminates first.

Re: Alternative finishes?

I'll let you know what I think. I have a gallon in hand (it came from Ontario I think).
The price was definitely right.

Alternative finishes?

Hey, I've always used Epifanes varnish for my cedar canoes. Like it. Just finishing up a kevlar/carbon/glass canoe... Looking for a more clear UV inhibiting finish. Has anyone used this stuff? https://theepoxyexperts.com/shop/coatings/max-seal-1-gallon-protective-clear-coat-aliphatic-polyurethane-no...

Re: 17' 0" Freedom

Got all the foam "installed" into one of the composite hulls last Saturday and put on the last layer of Kevlar on Sunday. Wetting out the kevlar was quite an experience. For every foot of linear distance down the centerline, the sides needed to consume about 13" of kevlar (due to the curve of the hu...

Re: Fiberglass & epoxy application during very hot weather?

As Brian noted, having a helper mix epoxy helps a lot. Things will go faster than "normal" at higher temps. Stay with the job well after you are "done" to check for bubbles forming (esp when glassing the inside if temps are rising). Look for opportunities to glass during times when the temp is decli...

Re: Sanding Epoxy inside hull

I found S-Glass to wet out just about as easily as E-Glass. I'm more accustomed to 4 oz s-glass however. I would say that it wets out easier than 6 oz E-glass (but there's 2 variables for you). It probably also depends on the viscosity of the epoxy you are using (I was glassing with West System epox...

Re: Sanding Epoxy inside hull

I'm a bit confused. Are you asking how much to sand the first layer of epoxy (with an intention of using two layers of epoxy (rather than 2 layers of glass?)? I'm assuming you mean two coats of epoxy (2 layers of glass would add weight you don't want)... You just need to scuff the surface to allow f...

Re: 17' 0" Nomad

I would address it now. How much flex do you have in the hull (i.e., how far do you need to push it to get it to the right place?)? If it is small, try putting some weight in it at that spot and let it set for a few days to see if it corrects. If that works, glass it as is. I would try to avoid reso...

Re: 17' 0" Freedom

Yeah, I was thinking of pouring sand into it but was worried about it sagging given the hull is pretty thin/flexible right now. I only have 2 supports right now (may add more) but will try my forms strapped in first.

Re: 17' 0" Freedom

The foam is 3/8" thick. It looks thicker in the pictures because I have beveled the edges ~30 degrees. I set up a jig on my table saw to cut fairly consistent bevels. It's pretty stiff stuff. I bought it from Fibre Glast https://www.fibreglast.com/product/Vinyl_Foam_4lb_Density/Foam It comes in a co...

Re: 17' 0" Freedom

I started with a layer of 5 oz kevlar
Next was a 6 oz layer of carbon fiber
Finally was a layer of 4 oz S-Glass

Inside I'll add (in the football and ribs up the side) 3/8" structural foam
and cover that with another layer of 5 oz Kevlar.

Re: 17' 0" Freedom

Still a work in progress but I coated the outside of this hull with a layer of heatshrink plastic to ensure nothing would stick to it. Then I wet out a layer of kevlar, a layer of carbon fiber and a layer of glass. Once cured, I pulled the composite hull off the "mold" and repeated the whole process...
