Removing under bonnet sound deadening?

[Lawbags]

Howdy all,

Any ideas how to get the last of this foam sound deadening off?
I've tried heat, petrol, diesel- all sorts but the last just won't come off without wrecking the paint.

Desperate to make it look good!

I would be more thinking about replacing it personally, but ultimately it is glue you are trying to remove, so Acetone or White spirit should work.

Warm water and fairy liquid?

And elbow grease

Looking at other work done to engine bay.
Would it not be easier taking bonnet of and lying flat to let tfr or the likes to soak in then scrape it off.

Toffee wheel/caramel wheel might do the job (this is the first link not necessarily the one id get or where id get it from)

White Spirit is my weapon of choice for this sort of thing. You ideally need to remove the bonnet and get it flat, so the white spirit can sit and do it's work. It needs to soak for a while to break down the adhesive. You'll struggle to shift it while it's vertical.

Start with WD40 to soften the glue. Then when that fails (like all WD40 "hacks") try a 50:50 mix of IPA and water. If that fails, try acetone. If that fails, paint thinners. But if I were you, assume that it might need repainting and hope it doesn't.

Depending what kind of glue it is changes the solvent - I would try neat IPA first. After that, as said, a toffee wheel

The reason for mixing IPA with water isn't to dilute it, but because water is a stronger polar solvent than IPA. It's also less volatile so a mix of the two allows for greater dwell time.

Neat IPA is great for many jobs, but when you are attacking an unknown substance it's best to try 50:50.
