When you do the vac on CF there is other stuff that
has to be applied so when its vac down it sucks up all
the extra reson ... I had to build a big bag to vac it
but I screwed up and didnt have my stiffeners on it when
I vac it down so I added them after but didnt vac them...
I could have gone with 2 layers of CF but I put 3 layers
on it.. if done right 2 is plenty... my hood weighs 6#..
my fiberglass one was 17# but that was with the scoop
