Headliner question.

[un4gvn!]

I used the 2 inch industrial strength velcro from Lowes. It's pretty sticky. You want to wipe both surfaces of the ceiling and headliner down with denatured alcohol. When you unravel the velcro, both the loop and pile will be stuck together. Leave them both together. Peel away the backing from one side. Press the velcro in an X pattern on either the ceiling or headliner. For extra strength, I cut 6 inch strips to attach to the four outer edges of the triangles you just made. Try to stay around 3 inch's in from the outer edge. Once you have the velcro tape attached to the surface, peel away the backing from the velcro. Leave both the loop and pile stuck to each other. Position the headliner where you want it. Once you have it squared up, press it to the ceiling making sure you're square. It's a real ***** trying to peel the headliner off to square it up. Take your time. Mine has been up for over 5 years now. No sags, no warping, and no signs of it coming off. I used the velcro because if I want to take down the headliner, there will be no mess from the glue remaining on the ceiling. I think the magnet will make the headliner hang a little low. The velcro makes it pressed up tight against the ceiling as you can see in the picture. The headliner is pretty thick, that's the reason I didn't use sound deadner.

To the OP, that looks amazing with no trim!
Awesome job!

All this talk about which adhesive to use, brings up a memory from many, many moons ago.

I was 16, and had a 1969 GMC truck that I was installing crushed velvet in.
I was doing all the work by myself, in my parents garage.
When it came time to do the roof, the only thing my dad had was contact cement.
I had the visors and mirror, and door seals all removed, as well as the interior light trim and lens, but I left the bulb hooked up, as I needed the light to see what I was doing. (Very poor lighting in the garage.)
I had most of the roof covered with contact cement, using a brush, and then it happened...
I swiped the brush too close to the interior light bulb, and the clip on one end tapped the metal of the cab and set off a spark which ignited the entire roof in a flash fire.
I ran out of the garage yelling, and my dad came running out of the house.
He always had a fire extinguisher on the floor, ready to go, and used it to quickly put the fire out before it could spread from the inside of the truck.

Very important lessons learned that day:

-work in a well ventilated area. (Outside is best)
-always disconnect the battery.
-always have a fire extinguisher on hand if there is any possibility of a fire.
-read the labels of products you have never used before.

It was a flash fire, so it quickly died off when all the glue had burnt off.
I was able to clean everything up, and still got the crushed velvet installed, which hid all the burnt paint of the cab’s interior.

That was just over 38 years ago, and I remember it like it was yesterday.

I should have used the Velcro, or magnets. Lol

Hey everyone,
Just wanted to give a quick update.
The 53 yr old headliner was too warped for a flush fit.
I got this new one from NPD. Along with using the velcro in my initial post, I'm really happy with the way it came out.
Thanks for everyone's input. Much appreciated!

Is anyone throwing some sound deadner up on the roof before installing their headliner?
It’s a huge, fairly flat surface, that could transmit sound...just thinking out loud.
I’d really like to add a headliner to the interior of our truck too!
