Started with a little experiments a few months ago, just something to keep me busy in between jobs etc.
Started out with an extra stock lid that goes on top of the trunk. Added a piece of plastic to lengthen it, melted it to shape and filled it with expanding foam
This was still super experimental, started to cut the foam to shape but to start over since I wasnt satisfied with the basic shape.
Also the third brake light position wasnt much to my liking. So back to the drawing board!
Felt it was too short to, so I extended it using a Citroen C3 rear wing thingy.
This was long enough, so I was off to shaping and smoothing
filled everything up, fill, sand, repeat.
sprayed some primer on it, more sanding. Tried to use lines to get it as closely symmetrical as I could.
Now I needed to fill in the underside too, I've kept the third brake light in its original location. Used foam and glassfibre to create a strong base.
Again, loads of sanding and filling to get everything nice and smooth.
Almost there! Have to figure out a way to shape the surrounding filler to fit the third brakelight nicely.
