Sagging Headliner
#11
I bought some material off ebay and redid mine.Not very hard but it is time consuming.You have to remove the headliner board which is card board with a fiberglass like coating.Scrape off the old foam(PIA!!!) and glue on the material and trim the edges and cut out the other little holes.Mine turned out nice.

Cool! Thanks, Dakota. I really think it will help with interior temps. Even though my truck is white I can feel the heat come off the inside of the roof when it is 90+ and sunny here, which is all summer long.

The problem IIRC is that the material used for headliners is a foamy cloth material. The foam starts to break down and then when you try to reattach it you are gluing back the broken down foam which will only continue to break down, hence it sags again. That is why you have to remove ALL the foam and crap and start with a clean surface, then it will probably stick correctly. It's like putting a new coat of paint over peeling paint, it just wont hold.
When I took my Camaro to be done I watched the guy at the shop and he had some glue in a spray gun (like a car paint gun) and he put the cardboard down and shot it with the compressed air like he was painting the cardboard liner. It was a thick yellow industrial looking glue. Then he applied and rolled out and trimmed the material. Like Mr Freez said, it's not really hard, just a time consuming PITA.
Miami, we actually have it pretty good. IIRC the Chevy trucks back in the 70's didn't even have a headliner, just the sheet metal. Trucks were more industrial back then.

I'm thinking it might be better to shoot expandable foam into the roof with a long wand. That would deaden sound/vibration and insulate without having to mess with the headliner. Could probably do most of it through the dome light and 3rd brake light openings. Hmmmm....

How? The roof is hollow twin wall. I'm talking about putting in that hollow cavity between the walls, not between the interior wall and the headliner.
EDIT: OK, I pulled the overhead and dome light and had a looksee. There are points where the inner and outer roof sheetmetal come to within an 1/8" between them. Looks like the expanded foam would have minimal effect in those areas. Guess I will go the route of dropping the headliner and using Dynamat to cover the roof area. Doesn't look like it will interfere with the headliner at all. Just a pain to undo all the crap to drop the headliner.
