After the mold is finished/sanded and cleaned we tested the bagging process and vaccuum on the mold. This helps to eliminate any surprises. We also had some experts from Lockheed (thanks) on hand to help out with suggestions.

Here is an intermediate sanding step between coats of primer sealer. We used 150 grit at first and the last few steps were 400 grit and up. A final wet sanding was done to finish it off.

In order to do a layup with prepreg we needed a large oven to heat the molds/layup in. We constructed a modular oven that could be dismatled and moved easily. The oven is fiberglass insulation at a suitable thickness reinforced by wire mesh and held on 2x4 studs.
