People may already be aware of this fix but not seen any photos on a how to.
Got fed up of my boot ratteling today so i had a play for 10 min with it.
You will need
1. Can of silicone spray (i used carplan dash spray)
2. Cloth to clean excess pray off.
It seems that its the outer rubber around the glass thats squeeking against the bodywork. If you push the boot down around the edges of the window you will hear it squeeking.
now for the simple fix
1, Open the boot and spray silicone all the way around the inside edge.
2, clean off any spray you have got onto paint work
3, close boot and test by pushing boot down firmly with one hand around the ouside of the window.
squeeking should now be gone repeat this every couple of weeks.
The red arrow points to the rubber thats causing my problem.
Again this is the problem area.
Red arrow point to ideal place to test for noise.
This is the spray i used 5.99 from local car shop.
