Headliner

What is your question?

So I bought this wonderful beetle, but it has a few cosmetic issues. I thought I was just going to buy a new headliner, but it turns out they are hard to find and expensive. So my next step is to fix it. I want to just take off the fabric from the backing and put on a cute fabric. My question is what type of fabric should I use and what kind of spray glue should I use? I'm worried if I use a typical spray glue I will get wet spots! And if I don't use the right type of fabric it won't look right! Help!
