Anyone know a solvent for un-heatcured firegum.
Or is abrasives the only option?

Humm,

Never heard of that product before, so I looked up the
Material Safety Data Sheet. Clean up is by dry sand,
vermiculite. I would say this would be in its paste form.
Also the data sheet did not list anything that it reacts with
as this product is really only sodium silicate. I think it is
going to have to see some crocus cloth action to be removed.

Cheers pb, although this stuff has not been heat cured, it does get quite hard and is a pain to remove.
I call all of these exhaust seal pastes "fire gum" cos that describes what it does.

yes, I did learn something last night, "fire gum" seems to be a
term that is used across the pond. I actually looked up the
Holts firegum for the information. Here in the US, we have the
creative name for the same type of product, exhaust patch paste.

I think "fire gum" has a little better ring to it.

I read this thread out of curiosity of what fire gum might be. By pure coincidence, I was talking to my cousin who is a full time Saab mechanic and service manager at a local Saab shop. I'm nursing a Durango waiting to buy my company car and the muffler is falling apart on the Durangol. I told him I was going to come over to the shop some night to patch up the muffler to get it thru to the fall. He said we could use muffler cement. I thought he was busting my chops. But he was serious. I did not even know they made a thing called muffler cement. Apparently we can patch up this muffler with the stuff. Should be an interesting process.
