Is it necessary to remove all of the old glue when installing a new headliner or can you leave the old glue in place and glue the new headliner over it?

John,
Removing the old glue is key to getting a smooth result. I removed all the glue and foam from my old vinyl (which I re-used after adding new foam) AND the roof. Not a fun job... but necessary.

John; Interesting enough, I just finished the roof of mine yesterday. I wire brushed the roof in which most of the dried foam came off rather easily. I then put a sheet of dynamat to the roof, and smoothed with a roller. I am also going to put a very thin pre-glued foam over the dynamat. I will then put a headliner on over the foam. My thought is to have the foam very smooth to have a very smooth headliner. In my opinion, to glue a headliner to the roof, the roof should be as smooth as prepping to paint.
after trying acetone ,mek,lacquer thinner ,which just made a mess. a product called goo gone and an old credit card as a scraper got the job done.keep wetting the surface using old towel @6'' square , let it soak in, then use the card to scrape the surface. it took multiple applications but took all the glue off to the metal. when all the glue was off i then used a little lacquer thinner to prep the metal for the new headliner.
I didn't get quite so fussy about cleaning the roof, though I did with the old headliner material. I noticed that the edges of the fabric had noticeable indents where the perimeter trim bits had sort of pinched it.
I cut a roof panel from 3/16" paper backed artists foam board and did a test install with the perimeter trim pieces and marked exactly where they laid on my new foam panel.
I removed the foam panel and glued the old headliner fabric onto it.
The marks I had made on the foam panel helped make sure that I got the fabric on just right, so the old marks at the edges of the headliner fabric would again wind up hidden beneath the perimeter trim.
Worked perfectly, and I've now got some small degree of insulation up there as well.
Best part was the gluing was done outside the cabin on a workbench, rather than upside down inside the car.

good ideas Larry. Sounds like a good approach to fix mine!
