The jobs this catalog gets built for, and the materials each one calls for.

01
Lightweight body panels
carbon fiber or fiberglass hoods, fenders, splitters, and diffusers laid up in epoxy for weight savings over steel or stock plastic.
02
Mold and plug work
pull a mold off a finished panel, then lay up repeat parts in carbon or glass with a gelcoat or surfacing layer for a class-A face.
03
Body repair and patch work
chopped strand and woven cloth set in polyester or epoxy to rebuild a cracked or holed fiberglass panel, then fair and refinish.
04
Interior and trim parts
light cloth and resin for dash panels, ducting, and covers where a stock part is heavy, brittle, or no longer available.
05
Aero and ducting
fiberglass or carbon ductwork, brake cooling, and undertrays faired with microballoon filler for a smooth, low-drag surface.
06
Structural bonding and fillets
epoxy thickened with fumed silica bonds panels, tabs, and brackets that carry real load.

Frequently asked questions

Can I make a carbon fiber hood or fender from a stock panel?

Yes. The usual path is to pull a mold off a finished panel, then lay up the new part in carbon fiber and epoxy inside that mold. You get a part that matches the original shape with the weight savings and look of carbon. The carbon fiber line plus epoxy, mold-release, and surfacing supplies cover the whole job.

Should I use epoxy or polyester resin for an automotive panel?

It depends on the job. Polyester is the cheaper choice for fiberglass repair on an existing polyester panel and for parts that will be gelcoated. Epoxy is stronger, bonds to almost anything including cured polyester, and is the standard for carbon fiber layup, so reach for epoxy on structural parts and any carbon work.

Do you stock carbon fiber cloth for body panels?

Yes. The carbon fiber line carries plain weave and twill cloth in the widths builders use for hoods, splitters, diffusers, and trim. Carbon and fiberglass both bond cleanly into an epoxy laminate, so many builders run a carbon face over a fiberglass backer to control cost.

What do I need to repair a cracked fiberglass body panel?

Grind back to sound glass, then relaminate with chopped strand mat and woven or biaxial cloth in polyester or epoxy to rebuild the thickness. Fair the repair with microballoon filler, then prime and refinish. The catalog stocks the cloth, resin, fillers, and gelcoat for the full repair.

Can a shop or race team get bulk pricing?

Yes. Body shops, fabricators, and race teams buying cloth, resin, and supplies on a recurring basis can apply for a Wholesale Pro account for catalog pricing. Apply through the request a bulk quote link on this page.
