This is what it looked like when we pulled it out of the sandbox.
But instead of releasing the shock guard from the mold, we laid-up another layer of fiberglass. The heavy matt didn't conform to the compound curves very well, so I ended up cutting in into smaller strips.
Let that dry and then pulled the shock guard. Made a pretty good mold, and we only lost a little bit of detail around the edges in a few spots.
So this morning I taped the shock guard back into the mold and poured some more resin to fill those spots where there were some small gaps. Not sure how well that's going to work...
