RE: Inside cowl muffler
BTW, pink foam insulation from a home improvement warehouse is also a great material for this application. Blue foam insulation is the same stuff. whatever........
It's absolutely easy to use. I've considered "boxing" instead of "tubing" my muffler tunnel. The foam would box it off perfectly. And might be easier to create than a tube.
I've used the stuff inside cowls as baffles since discovering how easy it is to use. And how much space it can fill. And that it coats with surfacing resin to be completely fuelproof. And that strengthens it if that's needed.
And darned if it doesn't insulate too. amazing........
