Mine is starting to come away. Is this normal spray adhesive please or does it need something more suited to the heat? If so, what should I use please?

Thanks in advance

I did mine a while back when PlasticMan repaired the front of my car with a new lightweight bonnet. I used high temperature impact adhesive from Car Builders Solutions. Its been perfect for 4 years.

High temperature are the operative words. I tried a can of carpet glue I had to hand - came straight off again!

I used some heatproof mastic/adhesive for a wood burner which I got from Amazon.

ETA - Victas Black Fire Cement.

Seems to have worked.

NO MORE NAILS the Tape easy to put on and the heat from the engine cures it and it will not come again.

Worked perfectly for 5 years now.

No mess either.

do make sure you use something that DOES stick! mine was stuck for 2 years, then i had some work done on the bonnet. i am not sure what they used but i smelt burning and opened the bonnet, the soundproofing had fallen off and was smouldering on my nice new clives y piece. the bodyshop have since used something else and cleaned and polished the y piece. and its been stuck on ever since.
it could have been worse!

Go with the high temp impact adhesive. Instant adhesion and job done properly not diy glue bodged ;-)

Thats the stuff. Good for interior carpets as well. Remember it gets very hot inside in the summer.

+1 for the glue chimjunkie advice's you to use "hi jon"
it withstands heat and its a contact adhesive , make's it easier to put the heat shield back on the car when fitting it

the garage I bought my car from used normal contact glue against my advice and it peeled off in the summer with heat build up
they then had to remove the adhesive to the underside of the bonnet and use the correct glue and its been fine since

make sure you get all the old glue off before you apply the new contact adhesive

Sounds like good advice. What did you use to get the old glue off please?

I tried various adhesive/tar removers and silicon remover on a small test area all with out success...be careful I've since read about someone using thinners/solvent which soaked through the fiberglass and micro blistered the paint on the other side.

In the end the easiest method I found to remove the old glue was to place the bonnet on a table with lots of bubble wrap under to protect the painted side and use a paint scraper...the shavehook kind with a triangle on the end with a curved side.

Be warned it sounds like finger nails on a black board and takes a good few hrs to do a whole bonnet.

Bought new Heat Shield fabric from CT along with their recommended high temp silicon (which turned out to be Wynns Black Gasket maker)to stick it on...worked very well but required 3 tubes to do whole bonnet.

TV8 , you want to use a thinners/ and scraper if possible to soften it up that's what I used I didn't have a problem with it going through the fibreglass ?
but put in on a little at a time enough to remove the old "don't pour it on and let it run everywhere" control what you are doing
and you should be ok

try evo stik remover as a thinners , cellulose thinners , white spirits and see what works best for you it all depends what product was used before
let us know how you get on !

when putting the heat shield back on another pair of hands comes in handy

Wait for it to warm up a bit before you do it. I flipped mine over on an old duvet to work on it, perfect!
