Carefully take apart the layered glass w/tweezers or other useful tool. You'll be able to see mat, bidirectional stitchmat, roving, and cloth.
Write down what you find, something similar to your findings will be your new schedule.
George,
Did the burn test yesterday on a scrap piece of transom from the TRS cutout on my Mag sport, it was not so easy to determine each individual layer of CSM, but it was very easy to see and count 4 individual layers of WR in the total layup. I think layup schedule should be something like this, Gelcoat, 2 Mat, Roving, 2 Mat, Roving & Roving, 2 Mat, Roving, 2 Mat.
In the middle of all this I did find 2 Woven Roving back to back. Quite a layup schedule!........................9/16" fiberglass!
