I'm with you on the foam bucks for fiberglass. There has to be a better way.
Back to the carbon parts, Ive finally got a plan of action for the inner fenders. I picked up these cheap plastic trailer fenders that happen to work very well for the plan I have envisioned for the mold. Im having a very hard time putting any kind of paint, bondo or sealer on the foam (styrene). It distorts too easy under the smallest amount of heat from the curing reaction. Im hoping the plastic will be easier to work with in that sense, just harder to find the complex shapes I need.”
Some guys are using expandable foam to make molds, check YouTube. Looks quick.
What is the width at the top of your rear l88 flares? Looks more than 4”.
