Hello guys my name is lee. I'm a welder fabricator and composites is a hobby. I've made a few Fibreglass items with success thanks to the easy composites video tutorials. Anyway I'm looking to make some Fibreglass fairings for my motorbike for track use and want some advise for making the molds. Obviously I'll use the original fairings as the plug but How should I go about filling the openings where the headlights and tail lights go without modifying original fairing? I want to be able to reuse them. thanks in advance

Thanks for the reply problem is the openings are curved shapes so flat board won't work. Thought about leaving lights in and using wax to seal around them. Thoughts?
