My headliner was sagging. I did this once on a '94, with school logo embossed onto new felt.

Had the How-To posted here, but it was before the server upgrades a few years ago.

This was the old one:



So again here:

I put a butter knife to the edge, to get under it. Make sure to hold the knife flat on the edge, to not scratch...



Then you can get a hand in.

 

Once you get under the edge, ya' gotta' pull the fabric off of the panel with your fingers. Don't try to pull it by the edge of the foam board - it will break up.

Wear long sleeves!

Go all the way around the edge, then work toward the center.

(at this point, the edge DID break, and I had to go around the other way)



Lifted. Lots of glue at the center.



I'm goin' with C4 logo this time, instead of school logo. I have a couple more of these, if anyone wants one here; PM at me.

 

Once the old felt is removed, I put a roller with Acrylic Latex Black to the foam pad, to stop dust from falling through the felt, and to give a little strength to the pad.

I also glued a 3/16" styrofoam board, cut into sections, to the roof panel side of the foam pad. I'm looking for noise absorption too with 3" exhaust, and a HEAVY drone.

Then I placed the felt, and flipped back the felt to apply glue to the lower half (using this for adhesive -
).



Then the top half,



and allowed it to dry overnight.

DO NOT PRESS DOWN TOO HARD - THE ADHESIVE WILL COME THROUGH THE FELT. You could see that in the 'Skully' '94 top...

 

Then flip it, and cut about 3" around the perimeter.



The forward corner concave curves are tricky. I made 2 cuts in the apex of the concave curve, to about 3/8" of the edge.



Flipped; check interior surface:

(same snappic, #3, post 2 above)

Now back up-side down, pull the tape, and glue the overlap...

 

Glue the lip to the panel side - I'm using RTV Black:



Re-tape, allow to dry, then set the pad into the panel.............

 

Done.

Felt glue onto the roof panel:



and set into place:



I did not cut the overlap deep enough into the front corner concave curves, and I got an ugly buckle on the D side.

And I placed a 3/16" styrofoam board glued onto the panel side of the pad, for extra exhaust drone kill. I have a glass top too, so I can measure interior sound with that top, and then again with the insulated Black top (when the rain stops)...
