Taking weight out is worth it. but to change/manufacture youself the parts from fibergass is not the first thing on the to do list on my next project. My target is still to lose 100 kg from 830 kg Lupo 3L. So I will need composites to reach that target that is certain.

This topic was for manufacturing parts with fiberglass.

So here is one tip.

Laminate over the old maybe even negative release anlge part one or two layers of thin 300g/m2 twill glasfibre. After it has been cured you can take it first off because it will flex so much that you can remove it from around that part. after that support it to its correct shape and apply more layers inside the part. This way you dont need to make mold of the original part which takes time and money. You need to sand that new part which you manufactured but it takes less time than making a mold...
