I have watched the repair video for the kayak hull cracks and need to repair mine. I ordered the different carbon-kevlar sheets (210gm Twill and the 188 Plain Weave) as listed. When I reviewed the video, I am not sure which sheet to use and where? For the two-layer reconstruction do I use the 210 as the base with the 188 as a top layer or visa versa or use either the 210 or 188 for both layers. I have a cracked front hull below the waterline and a left-sided cockpit compression fracture. Thanks for your advice.
