Nidacore panels from LBI showed up with 18 oz 0-90 woven roving. Weird white colored resin for the glass. I need to ask what it is, exactly.

The vinyl-ester resin I use turns white like this when cured. It starts out a redish bay brown color and once it starts to kick it turns whitish and once fully cured it is very white like what you have here. I read on the web about it before I bought mine and it is use for different reasons. One that I like is that it covers easy and you can paint over it with out much bleed threw of color. Also the under side of hatches and such may not even need to be coated at all if you are good with the look of the white. Another good thing about this type of resin is that it dose not shrink at all like most resins. It stays the same size or will actually will grow slightly. This helps retain shape better and you get less warping. It is mainly used for infusion injection molding but I have been laying it up by hand and what I have is thin enough you can easily vacuum bag with it. I was unsure about it at first but after using 50 gallons of it I like it.

Here is the resin fully wet:


In this picture you can see it start to turn white first at the edges where it is thicker and kicks off faster:


In this picture it is almost cured white no paint just bare resin:


This is the same lay up as the first picture but now cured out but still just bare resin:

Weird. Mine starts red-brown, then stirring in the MEKP, it goes red-green. Brushing it on it still has this translucent red-green-pink hue. It cures sort of yellowpink, like ginger root. But it is in no way white or opaque.

I believe I have Vipel F010-TBN-28 with a cobalt (napthenate) accelerator for room temp cure.

The elongation is 6.2%
