Any good tips for this? Mine has been crumbling for a while and I want to remove it. I removed the foam but there is a layer of adhesive left behind and it looks like it will be a bu**er to remove. :evil:

Cheers.

I'd try a solvent like brake cleaner,but don't use it on a on a hot engine & DO NOT get it in your eye as it hurts like hell AMHIK!

Hi :)

It is an absolute b*****d to remove...eventually I bought 4 cans of Glue remover from CPC, which worked perfectly...spray on...wipe off...etc.

Someone recently told me petrol works well , but be very careful with it lol....

All the best Brett :)

If you find anything better let us know. Still havn't done this with mine yet........ Quite fancy some of that reflective stuff like foil but it costs an arm & a leg.

Cheers for the tips fellas. I will see about getting some glue remover and try that. As usual a fingernail seems to work well but it will take forever!

Hi :)

Ummm not sure foil would be a good idea....reflecting all the engine heat back into the engine bay, might make it overheat....

The padded stuff as far as I know is to cut down noise....not heat...

On my 928 I have removed all the bonnet pad and just have clean blue ally...not noticed any difference, but mine is a "little" noisy anyway (think 130 Db on full chat)...lol

All the best Brett :)

WD40 sprayed on, left to soak, and then rubbed off with a towel moves most sticky residues. Everytime I have removed badges off things I have used this method to get rid of the sticky backing that's always left on.

All the best Brett :)

I would agree about the foil it will probably reflect too much heat back into the engine and cause problems, you can buy replacement foam sections from Porscheshop from memory around £60 per side but I would probably leave it clean once you have the glue off same as the S2 that has no foam under the bonnet except for a tiny square over the middle drivers side about 6" sq.

Correction to the Porscheshop price £36inc VAT either side so £72 both sides not too bad really and if you can't get the glue off completely just stick some new foam on top.

250 T never had foam either.
My first one got badly sctatched by a cat sleeping on the bonnet on a camping trip.
If I'd have caught it I'd skinned it as I'd just had the car Teflon coated.

Is it the NE meet this weekend?

The adhesive is an absolute swine. I have given up. I spent a few quid on some 'sticky stuff' remover from Wilko's but it was like headbutting a brick wall. I will try the glue remover that Brett suggested next. :x

Petrol is the best glue remover on the planet and the cheapest.

Be careful with it though :bom:
