I've finally gotten a mold made for my bmw e30 racecar trunk/boot and I am starting to plan out the layers of materials so I can infuse the part.

Are there any general recommendations on how many layers and core material to use? This will be basically just a skin part (I won't be making the inner structure like was done in that mini cooper bonnet video from easy composites) that will be pinned to the car. Obviously the car is only for track use so lightweight is the goal, without being to flimsy.

Thanks for your help!

Still going with this project :-)

Im having a hard time getting the Rohacell to conform to the near 90 curve in the trunk lid. I'm using a heat gun and that seems to be fine for slight bends but this angle seems like too much maybe? I'm thinking about splitting the core material into 2 pieces - 1 for the larger flat part of the lid, and a 2nd that spans the lower portion with the emblem (as seen in the poorly edited photo below). This seems less than ideal in my mind but I feel like I am otherwise potentially cracking the core. Any issue with doing it in 2 pieces, or advice on getting it to conform more to the curve?

Thanks as always!
