has anyone ever used the glue that you can spray on your headliner to keep it from sagging? or would you recommend replacing the entire headliner.

 

Most upolstry shops will put a new one in for 100 bucks. that spray glue will discolor, and leave ugly bloches.
Was your jet hot coating worth it? I'm thinking about it myself.
Since you are having headliner troubles, check my bost entitled "IF I build this stuff, would people buy it?

 

Once the Headlliner starts to sag, its time to replace it.
No Half-A-- repairs are going to help it.

 

the headers were coated before i bought the car so i cant give you and before and after results. i can tell you that this is the coolest running camaro ive had yet (and this is my 4th one) i dont know if the coating has anything to do with it.

 

I've never been in an upholstery shop. What do they usually sell and what names do they go by?

 

Look in your yellow pages under Auto Upholstery Shops and get a quote from them.

 

You can actually do it yourself for about $30, I was surprised at how easy it was on my old '84 Z28.
Pep Boys sells complete kits and it actually looked really good when done.
Don't try to just spray that glue onto your existing headliner it just leaves splotches and will come undone again soon.
