Hood

The first two photos below are showing the coating under the hood. I spent some hours cleaning the hood, in vain. Later it turned out that it had some minor dents that would be difficult/expensive to fix in combination with rust in the front. Therefore I've invested in a "new", almost perfect one. The other two pictures show the locking mechanism of the hood, before restoration.

In order to mimic the original coating under the hood I turned to my beloved Teroson's "Telescope Pistol Multi-Press air assisted spray pistol" which previously had been used for sealing the seams before painting the chassis. I used Teroson’s MS 9320 SF which is supposed to be good sound and vibration dampener and can also stand the heat from the engine as well as oil etc. By adjusting the front nozzle, amount of sealant sprayed and air pressure you can get a lot of different patterns. If I opened the nozzle 0,5 turns, set material flow to fully open minus 0,5 turn and around 5 bar air pressure I got [almost] the desired structure. I probably should have lessened the material flow a bit in order to get the structure a little bit finer. If I remember correctly, I used 4, maybe 5, cartridges of 9320 in order to achieve the desired material thickness of 2-3mm. I’m very happy with the result and hope it will give a more silent ride.

Bowden cable for the hood, so far only two pictures of dirty screws...

Sound and vibration dampening of hood

Trunk lid

This is the first pictures of the restoration of the trunk lid. As I've mentioned under Putting it all together - Part III - spraying the invisible areas, also the trunk lid's DB7164 got a little bit too glossy. It's not as bad as it looks on the photo (taken with flash and in day light).
