Front - 200grm Pro Finish 2/2 Twill - 200grm Plain Weave - 2mm Soric - 200grm Plain Weave - Carbon Tape/Off Cuts around the edge to match the thickness of the Soric. Back - 200grm Plain Weave - 450 grm 2/2 Twill. Additional layers around hinge/catch mounts. The layer of plain weave after the Pro Finish is to ensure that the white of the Soric is not seen through the Pro Finish surface layer. To keep costs down you could use a mixture of Diolen and CSM .

How many layers to get to the 2mm thickness, they should be a lot!? wozza (21/02/2013) This is my usual Bonnet/Hood lay up. Front - 200grm Pro Finish 2/2 Twill - 200grm Plain Weave - 2mm Soric - 200grm Plain Weave - Carbon Tape/Off Cuts around the edge to match the thickness of the Soric.

Regards Warren I do exactly same layup as this (for the top of the bonnet) and I don't need an inside panel as my shapes are not flat so have more than enough inherant strength.. did lots of trials and this was by far the best for strength vs weight vs looks. if I need more strength I do the rear in a heavier cloth say 650grm and for unltimate strength both the second layer and rear layer are 650gram cloth.
