wow, i missed those shiny new parts those are nice!!
Yes, I will fiberglass the taped areas. That then becomes a male mold which I will finish sand, wax, coat with mold release, and pull a finished fiberglass part off of the outside. That gives me a smooth finish for the exposed surface of the duct which I will then glass in place in the air dam. I'll take a couple of photos as I go.What is the next step? Fiberglass the taped surface?
I'm really interested in what you are doing. I will have some similar things to do with my car.
The poster board is under the yellow tape. I just formed the scoop out of taped together pieces of poster board, then covered the whole thing in tape to give it some rigidity. Then I covered the yellow tape with clear plastic boxing tape which releases the fiberglass resin much easier than the masking tape. Finally, I waxed the clear tape and put on a final coat of PVA as a mold release agent. Once the fiberglass cured, all of the tape and poster board just pealed off the back side with no effort . The tape does leave some lines in the fiberglass, but they are shallow and easy to sand out. Here is a photo of a poster board and tape buck I used when I built the fender flares for my Focus track car, to give you and idea of the build-up.Is the poster board under the fiberglass mat?
