Hi Tim,

I will probably try either the bondo or the redevil "onetime" product 
on this toroid.  I will eventually make a 10x40 toroid after I learn 
from this one.  David from D&M suggested, I think, paper taping the 
duct first (I presume to save weight), applying the bondo, and then 
doing the fiberglass resin coatings for strength.  I'm thinking of 
applying the bondo and filling the corrigations, sanding, varnishing, 
and then adding the AL tape.  I suppose, I will find out how heavy it 
becomes and alter the process for the 10x40 toroid.  Dont know how 
heavy bondo is compared to the redevil product nor how much filling 
the corrigations will improve strength.
