Do starboard use colored Resin in the design of starboard boards ?
Specially black colored ?
I want a simple answer : Yes or No.
The answer and/or the no answer from this post is important.

Oh, I've seen you posted the same question in the Tabou-boards- and Fanatic-Forum.
I can't answer your question - I'm not from Starboard - but I just wondered what are you aiming with this question. Maybe you have an answer, since this forum is a discussion board.
However Martins sales pitch fits to this topic:
See Position 3:32. Maybe this statement makes one or the other insecure about how brands are working ...

I was using non water based black roller pen ink to make resin black for my fins. Add one drop to 20grams of resin and it becomes almost black, but transparent.
Of course, it's not an answer to your question.

No. At least not as far as I know. I have a look inside different Starboards now and then and never saw any black resin. Moreover, in the context of the JP marketing, I don't think Starboard have boards where you can see the fiber through the paint. The high end Starboards use a full wood construction and then you instead see the wood grain if you use a thin color layer.

Although I'm not a Starboard representative and can't answer your question concerning their use of colored resins (which I seriously doubt they use), I can offer you some information regarding pigments. Different colored pigments in the form of monomers can be purchased and added to polyester and epoxy resins to color them for opaque and transparent results. However, working with such pigments does add a bit of complexity over use of clear resins, since the amount of pigment can affect the catalytic process, especially if trying to achieve dense opaque colors. Also, the quality of your tape-off work really needs to be fairly well developed to achieve good results.
Really, in the large production arena, I think that most firms like Cobra International are using paints or photographically generated patterns to achieve their colors and graphics.
However, if you want to use pigments to color resins, I would suggest contacting Fiberglass Hawaii or Fiberglass Supply to either buy or learn more about the standard pigment colors readily available. Also, in some colors, they have premixed pigmented resins available. Without a doubt, the premixed alternatives take away some of the difficulty in achieving a properly balanced level of color, particularly for those opaque applications.

The resin inside fin boxes is black. I bought a new carve 121 and within days the resin in the fin box well just under the screws had shattered. This is not uncommon, but in this case the the resin fractured more each time the board was used. I informed the dealer and got permission to replace the resin. It was easy to remove the resin using a wood chisel and a mallet leaving the glass fibre of the box intact. I had black pigment for polyester resin but I ended up opting for the powder that is used to dye concrete. I mixed the black concrete dye with epoxy, plugged the screw holes with a plastic rod and poured resin into the well. It was then necessary to get the well level and measure that the depth was right using a callipers. When the resin began to set I removed the plugs put cling film on top of the fin root and wiped it with wd40. I then drove my best fitting fin into the box using a mallet. This pushed some resin through the screw holes and gave a final shaping to the resin in the well. The rein retained its black colour over the following three years that I had the board and was indistinguishable from the colour on the sides of the box.
When I sold the board I explained what had been done.
I regarded this course as an easier option than making a claim under the warranty, especially having been told by the dealer that this cracking is common and harmless.
The repair never cracked in three years of use and the colour did not change.
This is a statement of experience rather than a recommendation of procedure.
