Learn how to build a custom, lightweight fiberglass hood from scratch using an original steel hood as your template. We explain the core fundamentals of fiberglass fabrication, including how to shape a disposable “plug” with body filler, prep it with wax and release film, and pull a stable fiberglass mold that won’t shrink or warp. Perfect for any custom car project, this guide covers the essential techniques for spraying tooling gel, rolling out resin, and laying up a clean, one-of-a-kind final panel ready for a perfect test-fit.
