Just thought I`d say, your unlikely to have this problem with Dry carbon fibre as the resin is pre-pregnated and autoclaved. Where as the wet lay up carbon is a seperate layer of resin. So the top layer is prone to cracking and also warping and giving you a ripple effect. This is because the resins used can`t cope with temperature, so the sun heats up the resin and distorts it. Pre-preg carbon is baked in the autoclave 140 degrees, vacuum bagged and presurised, so the resin won`t warp. Just a food for thought when purchasing carbon fibre products. Better spending more on Dry carbon that will last a long time and look spot on, than waste your money on repairs and a shoddy looking product. Also the final product weighs much less due to a less resin used.
