+x Hanaldo - 1/15/2018 2:10:27 AMSo this is a front splitter I made for a Porsche recentlyI made the top skin of the mould as per normal, flipped it over and then set up barriers to make the overlap section of the mould.When that was cured, I removed it without demoulding the top skinAnd then the bottom section is laid up as per normalNow in this case, I wasn't actually trying to keep the leading edge smooth, I just wanted a recessed overlap section for a better bond. So I placed the sheet wax on the overlap section of the mould itself, but for a rear wing I would place the sheet wax on the bottom skin mould.When finished, you're left with this:In this case, when I bonded the two skins together, I smoothed off the join using the adhesive that squeezed out of the gap, so it was only visible as a solid black line but was very smooth.
