Hi there,
I bought a replacement for under the bonnet from USA company
JAGUAR
Worth looking at their site and video.
You definately have to take the bonnet off to get good adhesion and of course
use the correct adhesive spray withstand the temperature.
There are two bonnet designs, if your car is 92-96 I have a spare NEW insulation
minus kit and transfer I could sell you.
See link I put above…
regards
Haydn
