Audi 90 skies

nEvening together I just registered here, hope you can help me. … I bought an Audi 90 (NG engine) a while ago, but with a rough ramped sky. I have now removed the sky and scraped off the fabric as well as the foam residue so far. Since I like to do this myself and imagine a cushioner relatively expensive, I had now thought that I would stick the sky with PUR foam (5mm thick?!) and then stick the fabric on it (with “swift”) col 2144″ highly heat-resistant). However, the fabric is not particularly respectable, especially since foam and adhesive residues hang on the back, so I would like to buy new fabric. To my questions, has someone ever done something like this and can perhaps tell me where I get the foam best (have asked in some shops near already – misindication) and if there is a special designation for the color of the sky? The paint color is glacier blue metallic (LY5U), with the the sky was either white or always somehow grey, hang a picture to the equipment sometimes. Greeting and thank you already in advance
