Cleaning underside

I was lucky. My Traveller was bought from a very meticulous chap who restored it well- with lots of waxoyl/underseal underneath. I am now going round ,I hiped , every square inch down to the paint underneath.
Unfirtunately so much hard waxoyl and thick underseal I cant shift either. The underseal is 1/4 inch thick in joints and I like having a tyre melted sround it.
I also am lying flat underneath it !
I cant see a way around this!

I think a valid question is why do you want to take it off? If it is really sound and stuck very well isn't it better to leave it? Eventually the layers fail and water can get in between the metal and all the gunk. At that point all the underseal is actually harmful as water gets trapped (similar to wood rotting on wooden windows once the paint layer fails).

A heat gun is probably the way forward but it is going to be incredibly messy.

Not that it is practical at home but I watched a car restoration programme on television where they used dry ice. The extreme cold made the tarry underseal brittle and it could be broken off. The was on the floor on the inside of the car so the dry ice could be contained and it would not work unless you could turn your Morris upside down!

Are you sure its underseal it could be seem sealer applied to the joints, if so leave well alone.

Its underseal and waxoyl. The previous owner was proud to say. Painted first. I have uncovered a few patches where the metal is just starting to colour with rust. Sprayed thin Dinitrol on it and will go over it with hard black Dinitrol .

The good thing about waxoil is it protects without hiding so you can see if anything is developing.
