We used an industrial spray contact adhesive (meant to be the bee's knees) for securing the panels to the fibreglass walls of the engine compartment. Over a short time all the overhead pieces fell off and the side pieces have slid! As I followed the instructions I can only think that the glue can't cope with the heat in the engine compartment.
Has anyone had the same problem, and what glue would you recommend, please.

Have always used regular liquid evostick, not yet experianced problems.

Couple of silly questions:
did you de-grease the fiberglass first? new flo-coat has a slightly waxy surface, and old engine bay is likely to be very oily - hot soapy water and scotch brite.

did you put enough on? in my experiance spray's are used for light jobs such as sticking paper templates, and heavy jobs like lineings need liquid applied with a brush or trowel.
 
I used Evostick "Impact" solvent-based contact adhesive when I lined my engine compartment three years ago. I was surprised how much I needed (three or four 500ml cans, I think). It has shown no sign of letting go, in spite of the fact that the temperature in my engine compartment is typically 65 degrees Celsius when the engine is running. One piece is otherwise entirely unsupported on the underside of the trap door on top of the engine.

You can get quite high on the vapour, you have to get it right first time, and if you buy from a DIY store you have to hang around while they find the key to their secure room.
 
Just done the job. Evo-Stik 528. Can stamped Trade Only. Not available (I don't think) in the sheds. Got mine from Jewsons.
 
Be careful using Evostick in an enclosed space as it is highly inflammable.One of my friends fitted new formica worktops to his kitchen,some years ago,lit the gas and nearly blew his kitchen up.
 
The modern way is to use grab adhesive in a tube.

It's cheap, easy to apply and it works. Depending upon your requirements you can get waterproof, or solvent free, or extremely strong etc.

I normally use Screwfix's "No Nonsense" grab adhesive for most things these days, it's excellent and really cheap.

However, it isn't waterproof so it may not suit your application.

For my engine hatch cover sound insulation, which is heavy and exposed to fairly high temperatures, I used Evo Stik "Sticks like S**t" yes, really that's what it's called, and it's done what it said on the tube.
 
Second vote for sticks like sh!t , fantastic stuff ,fixes anything to anything .Used it on overhead sound insulation over engine ,tried a small sample patch first , tried to pull it of and the foam tore of the backing material ,had to get it of with a sharp chisel .

I have just got a can of special adhesive from ASAP. They recommend that overhead panels are also held by screws and their large plastic washers. Let's see how it goes!!!

i've just ordered this today too!
got the quietlife insulation ready to fit----is everyone saying it's not up to the job!!!
think i read somewhere people have used sikaflex too
by the way am i right in thinking some times decorators caulk can be used between the sheets to fill any small gaps ---ASAP didn't have any suitable tape when i bought the insulation--
