Building Better Bodies 1: Gelcoat

Here, the nose is being sprayed with gelcoat.

The molds have been waxed four times and coated with a mold release agent.

Wax has been used to fill in the seams of the molds.

Our doors are getting their initial white gelcoat.

Our project LeGrand will be gelcoated with International Orange.

A second body is also being made for a friend of ours. He chose to make it the same Signal Green that our car is painted now.

We’re creating new, fiberglass LeGrand bodies using the original molds, and the first part of the construction is underway. The old molds have been cleaned, waxed, buffed, and coated with a mold release compound. The bodies are now being sprayed with white gelcoat.

Normally, the colored gelcoat goes on first. However, our molds turned out to be in a little rougher shape than expected, so we sprayed the bodies with a less expensive white gelcoat. After the bodies are laid up and popped out of the molds, we’ll sand the gelcoat completely smooth . Then we’ll spray the colored gelcoat, which will be buffed to perfection.

Would it be cheaper/less work to just repair or refinish the moulds rather than sand the new bodies, respray and buff?

As a tongue in cheek followup: Wouldn't having less gelcoat be lighter?
