Alright guys, time to wrap it up for the night
The passenger side quarter panel cured first, so I trimmed it up, tore off the cardboard (the stuff that I could), and then test fitted... looks pretty good. I need to hit it with a few more layers, but will do that after it's joined with the rest of the box.
I trimmed up the passenger plastic panel, and then inserted in the car for a test fit....
tomorrow, I'll spend some time masking both areas, and then starting on the rest of the mold.
