The front spoiler on a Ferrari 308 GT4 is one of the few options that these cars could be equipped with. Theoretically, this spoiler would help with high-speed stability. It also looks pretty cool, and collectors covet almost any and all factory options.

That is the good news. The bad news is that these spoilers hang low and are easy to beat up on curbing. That was definitely the case with our car’s front spoiler.

So, before the car could make its debut in the Michelin booth during The Amelia weekend, we had to first repair the front spoiler.

Less than a dozen bolts secure the spoiler to the car’s front apron. With the bolts removed, we could get to work.

We’re assuming that any body shop would charge at least a grand for this fix. We knew that we could do it for less–much less.

Within minutes, we had ground down the spoiler’s two rough corners plus the damage in the center.

Using small strips of aluminum sheet and self-tapping screws, we returned the spoiler to the correct shape again. The trick here: Glass over your aluminum sheet patches, let the fiberglass harden, and then grind out the aluminum pieces.

Then you go back over the area with fiberglass to repair the damage done by the self-tapping screws. Once you have ground and sanded the area, then you are ready for final finishing and paint.

The spoiler was originally had a textured finish, much like bed liner. We picked up a can of Dupli-Color pickup truck bed liner at a local auto parts store and resprayed the entire spoiler.

Once dry, we bolted the spoiler back onto the nose of our Ferrari and knocked off another item on our to-do list.

Nice.  My repair would need to be in some kind of a two-part epoxy or UV curable photopolymer, since I don't have much experience with fiberglass.
