Spray on sound deadener

Anybody used spray on sound deadener before? Either in a can or spray gun. What's it like?

I was going to spray it in the rear of the cabin as the factory sound deadening is removed and I don't have rear seats because of the cage. I wanted a clean look but the sound deadening looks like it sprays on abit rough. Any thoughts?

It's naff if u want a nice clean finish get some acoustic carpet and lay that on with some spray glue it's a much nicer finish and looks proper cosy lol but more importantly its cheap off flebay.

I had thought about carpet but not really keen on the idea. Just wanted minimise the noise abit
