Does anyone have a method of chemically removing underseal?
Any advice appreciated.

As per @Beneagles , or, and you have to be VERY careful and must work in an open space, soak with petrol
Now this might seem a little risky, but not if done carefully and methodically. Simply decant some petrol into a jar and paint on with a 2-3" brush. Allow the petrol to soak in for some 15-20mins and then scraper off. The old underseal will simply fall off after a good soak/couple of coats.
Of course there are some safe working procedures when doing this:

Of course there are some safe working procedures when doing this:
- ventilation - garage doors wide open
- no heat/naked flames anywhere
- PPE must be worn
- suggest putting old carboard boxes under full length of car to catch all fallen underseal/Waxoyl/Schultz
- once petrol fumes have spent the old underseal can be swept up into a bag and disposed of.

If you are using petrol please be ultra cautious. You have two major things to consider if using it;
Fire risk. You are potentially going to have your hands soaked in it so if the **** does hit the fan you can't just tackle the situation in a normal way. Remember that petrol fumes are heavier than air so can linger in areas. Also think about disposal of rags etc. I am not sure how easy the fumes are to ignite, but beware of sparks from static and any electrical power tools etc. Perhaps a foam extinguisher on standby?
Fumes- I once changed a leaking petrol tank on an old Sierra. Struggled getting it off due to corroded fixings so ended up breathing the fumes for way longer than I should. Really suffered with it for a couple of days. I would not use it anywhere that is enclosed as I would want any wind to constantly clear the fumes.
Personally I would have thought a hot air gun and scraper would be more controlled.

Then any residue...acetone and a scotchbrite will finish it off...thats my prefered method...

Acetone brings back bizarre memories of running down the middle of the main Weapons Shop in Portsmouth Royal Dockyard, having sat on a rag soaked in it...

Ouch! Acetone is an horrendous solvent to be corporeally absorbed. I spilt some on my foot/toes whilst wearing sandals. Took 9mths before skin / tissue was fully healed, especially between the toes. Far worse, a friend kept working in his acetone soaked overalls, ignoring the burns/not realising the burn severity despite flushing with water. He was rushed to hospital that evening, had an extreme allergic reaction, went into a near coma[!!], was released 1week later and now has permanent skin sensitivity over both legs/feet/hands and some crazy dermatitis. Dangerous stuff is acetone...

I was cleaning up the sealing face of a Ferranti 909 weapons director cover; **** job, so the boy gets it.
To be fair, I did have full PPE, even in 1983, but that didn't cover my arse.
Thirty minutes later, I was still sitting in a washbasin full of cold water and Swarfega.
