il let you know mate hah. It will be a case of waiting for a scorching hot day and see if any of it starts to sag.
it all went on great, but whether it will stay that well stuck to the roof is another thing.
I actually used a combination of glues. Just a normal spray adhesive (normally for sticking carpet down on speaker builds) on the nice large flat surfaces. Then the contact adhesive on the bits where the suede sat in groves/needed to be stretched slightly.
