....last time I was at SAILS, just outside Montreal, I purchased surplus asbestos mitts.... probably intended for foundry use..... brand new for about $10.00 they are made out of course wooven asbestos in one bulky piece and the one stiched seam could be undone quite readily.... total surface area about a square foot. It might be just enough to place over whatever commercial blanket such as Duramat and extend the temp. range enough to work for critical areas such as near the exhaust manifold/engine cover.

I do have some 1/4 inch rigid asbestos board but would be useless for sound deadening.
