I made a little more progress on the trunk. It is slow going for a dope that has never done this before.
I got a piece of plasti-card and marked out the outline.
I also trimmed off the bracing from the bottom of the trunk lid.
I then added back a bit of plastic to replace the amount lost by the cut.
I cut out the opening of the trunk leaving a gap around the mark I made earlier. I also backed the face.
Then I was able to add the bracing back on.
Finally I added a band around the trunk.
I used Revell Contacta for all of this work as it creates a strong bond. I also added a bit of quick dry Tamiya for good measure. I will let all cure overnight before sanding it down smoothly.
