Do you have any pics of stuff you've made with the flakes? I'm definitely gonna do a test piece first
One fin I made out of Ipe wood, I made two halves and I layered seveal pieces of 7.5 oz cloth for the center of the fin and to compromise the Halo. I used Epoxy, I am not sure which brand/type but it could have been Apex or System 3 SB112. It was 10+ years ago.
Anyway when I peeled it off the glass and held it upto the light it had similar characteristics to what you are looking for. My 7.5 cloth was old and did not go completely clear in all parts, I have no Pics, but remember at the time thnking about making a panel using 3.7 oz E cloth with a water white epoxy resin could look quite neat with what it did to sunlight passing through it.
My Choice for this would be System3 Clear coat resin as it is very watery and very clear, and cures slowly ( 60 minute pot life at 75f) so One could take their time laying it out and getting all bubbles out.
I don't know if the sparkly finishes of surfboards attract predatory fish, but Hawaiians are known to be superstitious. My grandfather was born when Hawaii was still a kingdom. He was very strict about following certain beliefs.
In the old days of Hawaii, one type of wood used for canoes and surfboards was Wiliwili. It is a soft, very light wood that we call Hawaiian Balsa. It is very light in color and often has a lot of figuring. The hulls were usually made from Koa, and the outrigger parts from lighter wood like Wiliwili or Hau. Koa is dark, very hard, but heavy. Some canoe hulls were made from Wiliwili. There are stories of how sharks would attack the canoes with Wiliwili wood, but not Koa. It could be that they knew the wood was softer, or it could be the way the wood looked. Wiliwili surfboards were usually only for the chiefs.
I only use Wiliwili on the decks of my boards.
Typical popular Hawaiian fishing lures made for trolling for large fish are made to look like squid, and have shiny metal flake finishes to reflect sunlight.
I decided several years ago to not use things that could cause light to shimmer or reflect and attract attention. Just being extremely cautious.
Straight clear, don't use warp cloth, twist weave 7-1/2 oz.
As said, slow batch, 36 layers and when done cover with stretch wrap and work out any remaining air with a rolling pin working from center out.
It gets the pearl look from the prism effect when light passes through
RE; JimtheG. Proof positive why the old timers are so valuable to the forum. Experience cannot be underestimated.
Alright sounds like I will now be doing two panels! One with the flakes I already ordered and one as jimthegenious reccomends. The prism idea does make sense
Well I layed up the panel with 4 layers yellow tint in between the resin with flakes. Sanded finish looks pretty much brown but the glass side of the panel had the pearlescent effect, so it should be there after gloss. Here's the rough foil, gonna fine tune and hotcoat tomorrow
Just needs a polish and the holes drilled
Just looks like Volan and ISO to me. Most clear Volans will refract light when held up to UV. Might be straight Volan and 249A. Pearlesque powder in the lay up causes refraction as well. Just an educated guess. Lowel. PS You won't get that kind of refraction out of a tinted panel. But your yellow tinted fin looks good.
...you can obtain that color like J Phillips is saying and with heavier plain volan cloth, twill; biaxial etc. A tip is to not lay down exactly all the layers, then between the thickness of those volan strands + the difference in the orientation you obtain such color. But I tell you that looks good in those photos but with time and in positions where do not have the light effect would not look so interesting.
