Tyler,

I used fiberglass resin on my last two secondaries I made, and it worked 
pretty well so far.  I can't say how long it will last, but it seems pretty 
sturdy.  What works best is to have the coil mounted on whatever you used 
to wind it, with appropriate drop cloths, then pour a thin stripe on and 
smooth with a plastic squegee.  Be sure the resin is thin enough to prevent 
bubble formation.
