Roof lining

[wooden plane]

This may be in the wrong thread but You fellas would definitely be more expert than I am at this.
I have an old 1992 Toyota Troopie and am taking it around on the "Grey Go-mad" tour next month, Slowly modifying bits and pieces and the other day and I noticed that the roof lining is hanging down in places, I dont want it flopping down on us while we are sleeping in it or while driving so how do I do a quick but effective fix on it.
It's probably isn't worth doing a complete new liner job on it, the old girl is costing a lot already, ( so is the car). I would welcome some simply and easy suggestions for a simple man.
Ta in advance.

Posting a couple of good mclear photo's would help, it will make a decision much simpler, very difficult without seeing what the situation is

Thanks China
I will have a go at the photos, last time I tried posting them I made a hash of it and have given up since, will try again. The lining is old and is only dropping along the rear edge so far, I would like to arrest it before it gets any worse. I was considering trying to inject some latex glue through the lining and then pressing it back onto the roof but don't know if I'm liable to make a mess of it. Maybe some spray adhesive?
Thanks
Mike

Spray contact adhesive should work as a reasonable fix, but depends on you being able to rip enough of the liner down to spray the fabric and the foam before re-application. Handy thing is that provided you wait till the glue goes tacky, you don't have to support it once you've pushed the liner fabric to the foam. Should also work in the areas where the liner goes straight onto the metal.

If you're having issues getting a hold of a decent spray contact adhesive, I've just brush applied before and it works fine, but you go through buckets of glue as you're driving it into the fabric/foam instead of just laying a fine coat on top.

Just make sure that you have all of the windows open, that stuff really stinks and can ruin your sense of smell for days with all of the solvent that normally comes off it.

EDIT:
Note that the liner glue normally fails after hot weather and normally gets pretty weak all over, but only actually falls off in patches at a time. This can develop into an annoying situation where your previous fix actually makes it difficult to repair future failures. I'd suggest that if you are considering re-gluing your liner and going to the extent of buying spray adhesive (which has a lifetime in the can), it wouldn't hurt to pull the whole thing down and re-do it if you're able. Just make sure you go slow with the pulling, as the fabric also tends to have weakened off at the same time as the glue and may tear.

Whether you can succesfully inject something thru the lining to press it back to the roof depends on how much dust has settled on the inside of the lining & whether any underlying foam (if present) is starting to break down. It only takes a thin film of dust/crumbly foam to stop whatever adhesive you're using from binding properly. DAMHIKT.

To check - and to clean if it is dirty - means un-tucking enough to actually eyeball it.

And if you're going that far, you're better off using contact adhesive as themage says.
