Anyone do turbo blanket and downpipe/testpipe wrap?

Thanks for the tips.
Wet, as in water? Does that help wrap stretch or something?

What about the can of silicone spray I got with the stuff (Summit Racing)?
I haven’t read directions yet so I don’t want to sound like an idiot. I’ve never wrapped headers on an N/A car and never had reason to wrap testpipe and downpipe on any turbo car I’ve had because I wasn’t putting down these kinds of numbers, but my temps are a little high and I want to be able to get them down some so I can bump up timing on the race gas file.
