i can get some exhuast heat wrap for next to nothing

and was thinking since the trusty old rotator isnt crossflow, might be useful to keep some heat away from my weber

would also upgrade the appearance of my exhaust a little as no type of heat paint cant actually stand the heat!

but i have heard that the heat wrap can hold moisture prematurely rusting your exhaust... so im not real keen on that idea

any opinions/experiences?
