Under Bonnet Sound Insulation material

[v8250]

I'm wanting to replace the under bonnet insulation on the MGB, however, I do not want to replace with the original heavy Hardura/Bitumin/PVC felt-backed type of material. MOSS sell Dynamat, which frankly, is just hugely overpriced.

I'm looking for a modern black material that's designed for under bonnet type applications i.e. sound absorbing and heat resistive. Could anyone direct me to the right supplier / have a good suggestion; thank you.

PS have looked at Europa Spares, MOSS, MGOC, Woolies, CBS etc
