What you are looking at is a clear smoke tint through the bottom one-third lay-up (ie read the trailing edge of the fin) and then a white opaque (ie pigment) followed by a black opaque on top
Hi Kev, thanks for responding. These are the buggers. You can see they are layed up in three 'layers".
Each opaque lay-up reqires a hotcoat (fillercoat) between them to preserve the integrity of the laminate (ie the line between the colours) so we have something like 5-6 seperate lay-ups to produce this one panel that you are looking at (and about 30 layers of cloth..dependent on weight of cloth)
It is commonly known in the industry, that opaques DO NOT FLEX (and they are used to stiffen glass) and the only way that BLACK and WHITE can exist in resin..is by an opaque method (meaning solid colour)
All true FLEX panels were layed up as CLEAR (green) or a TINT (ie transparent colour of whatever description)
Yes it does, because it has NO MEMORY and no memory = a negative flexural characteristic
I think the pigment alters the flex characteristics
Hope this is of interest to the thread
