Yea I got lucky, it was leftover material from a boat he was doing, and I'm sure he gets the glue for wholesale nothin. So it was probably 90% profit for him.
This is where it pays to pay someone else to do it lol. I made more than that using those hours to work.
All the work is pulling it out of the vehicle. I used to get mine done for $75 when I would pull it myself and that included the proper headliner material. I am sure it's more now, that was 10 years ago.
I always took the GM headliners to the shop because they use Styrofoam for the headliner shell. If you use a strong glue it shrivels the Styrofoam up and ruins it, been there, done that.
All the Fords I have done so far have been cardboard shells. That holds up to the stronger glues you can get at the hardware store, and I either go to a local fabric store, or some Walmarts have a fabric section where they sell vinyl. I found some tan colored vinyl a couple of years ago at my local Walmart and that is what I glued into my Bronco II.
