Hi all. The insulation on the inside of my firewall on a GU4 is breaking up and cracking. There is a big patch that has all broken away next to the left foot rest. Im after some ideas on repairing it so it doesnt keep going. The same insulation on my series 1 is still pretty soft and no damage at all. This one is all hard and brittle all the way up under the dash and is cracking everywhere.
