If I remember correctly there is a Buddy Craig vid on You tube. Might see if your could find it. Try searching, "Fiero headliner" over there. Also might try the same search here on PFF. Tons of threads. Here is my half hearted attempt to recover my headliner. Mostly shock and comedy at the previous owners expense! http://www.fiero.nl/forum/A...130314-2-120201.html
Use a green scrubbie to remove the old dried up foam. Lightly brush it off with a dry scrub sponge. It should all just fall off. Don't wipe to hard or you will get into the fiberglass.
For myself, spray both surfaces to be mated with adhesive. Let sit for a few moments then carefully stick together. DONT use your finger tips and push hard onto the material. You will soak the material through and have finger print like dents everywhere.
Oh yeah, be very careful removing and installing the headliner. I left the seats in and used them to prop one side of the headliner up while I worked.
If I remember correctly you only need to fully remove one side of the plastic interior trim pieces.
That is about all I can remember right now. Definitely do a search here on PFF and educate yourself as much as possible. There have been TONS of discussions on what the best adhesive is to use and what is the best material and it's source. All in all it's a fairly easy Fiero fix. Actually can be fun and the results are VERY gratifying as you will no doubt see it every time you get in! You can do it and we are all here to help!!
One thing you need to do, is give the glue a little more time to set up. It is a contact cement. So it should be dry enough that when you touch it none comes off on your finger before you try to install it. Keep in mind, you only get one shot once it is stuck it is there to stay. Good luck
don't know if you have a sunroof or not, but if you do, leave a lot more extra fabric in the sunroof hole than you think you will need. It's always better to have too much rather than too little (you can always cut the extra out whit the headliner in the car). I found this out the hard way
Just got my car apart, and tried to lay down the new fabric. I have 2 problems. First, my board is falling apart so when I press the fabric into all the curves, it pulls back up and rips he old fiberglass. Second, the material I bought WILL NOT STRETCH therefore there is wrinkles everywhere!!! I just wasted my board, and my $90 material.
One more tip - I've done this about 5 times on headliners. Works even better if your headliner board is in rough shape. Get yourself some fiberglass resin and a tight napped roller - I use those disposable 3" wide trim rollers. Once the board is clean, mix up some resin and roll on a coat. let it dry. Rough it up with some 80 grit, wipe it clean and then apply your glue to the board and material. Like said above, make sure the contact cement is setup. The board will be ridged and the material will stick far better to the solid surface versus the pressed fiberglass surface. Also, later on when the headliner is back in the car, the material will not pull loose in the head wells of the board.
