the headliner now has stick pins holding it up, i know this is a problem with the older vehicles (94 3/4 4x4 ) i was thinking about just tearing it down completly, but i tried a small sectiion and either the old glue or the foam under neath is very rotted( i guess) because you touch it and the dust just keeps falling and falling, so i thought i might tear it all out , clear down to the metal, the only thing up there is 2 overhead lights and 2 speakers in the rear, but this beast does not have a/c and i was wondering about the heat from the summer sun, unless someone has a easy fix , i am not going to the hassle of replacing the headliner, but maybe i could catch a warm day and try using some cheap light colored paint and just paint the foam underliner , any ideas?

 

Masonite is fairly cheap and easy to work with. You can get it at any home depot/lowes/lumber yard in 4'x8' sheets. It comes in 1/4 and 1/8 inch thicknesses. I would use the 1/8" stuff. You can just paint it, or cover it with fabric. Make some cardboard templates first and get a nice fit with them, then cut out your board.

medium density fiberboard will work too, tho the masonite is more stable (masonite is a high density fiberboard, glossy on one side and dimpled on the back. I would use the glossy side for the inside of your truck. If you glue to it, scuff it up with some light sandpaper (120 grit, 220 grit if you paint it). A jigsaw will handle the cuts just fine, even a handsaw will work fine, it's easy to cut.

I seem to remember finding some even thinner. This would be fine too, maybe even beter.

Brushed aluminum sheet looks really cool too!

I re did a headliner in my moms 1988 carprice once. You should be able to take the headliner all in one piece out the back if you remove all the trim along the sides. Then when you have it outside, pull off the old foam backed cloth. Sweep all the old left over foam on the headliner board. You can get the material from a hobby or fabric shop. I know you can buy the kit online. Spray the headliner board with adhesive and lay the new foam lined headliner on the board. Let it dry for a few hours, then reinstall it. I think i paid under 20.00 for all the materials and it will look great. It was still holding when the car was sold 3 years later.
