Mine came off, I rubbed the loose yellow foam gunk off and got my lining back on with a stack of spray adhesive. Its a chit job. Get a few cloths and cover them in white spirits to hold and rub it to the roof as it sticks- as it will stick to your hands and come off. It doesnt stick to the cloth obviously. It took quite a few coats for it to stick but if youre patient it can be a cheap easy fix
