Im looking to refurbish my rear lining and eventually the front. The plan is to cover it with that black speaker box carpet, should look good and add a bit of extra sound deadening.

Though at a slight loss as to what to use to attach it, ive tried many a spray on glue even heavy duty stuff falls off after a few months or when it gets hot.

Only thing I could think of was using a mixture of HD high temp spray glue with some of that iron on stuff round the edges/usual saggy bits.

Good plan? Or anyon else got better ideas?

I used Trim-Fix High Temperature Adhesive on mine. I re-did the whole headlining using quite a thick lining material over 9 months ago and it hasn't budged at all. You do get through a bit and make sure you spray both surfaces but it does seem to be doing the trick. Even after a few hot days this summer no issues. It will probably help if you put some insulation between the headlining and the roof.

Cheers mate. Yeah planning on 10mm closed cell foam

I was considering installing this stuff, very similar to NOISEKILLER Egg box form.
