Re: Sonotube loss corrections

"After heating as Eddie suggested, then apply 3 coats of
G.E. Glyptal to both inside and outside of the coilform before winding. 
Allow 12 hours to dry between each coat."

	Sounds like you are using clear glyptal.  Any idea where I could get a
few ounces?  Seems to me I've asked this before, but only found source
for red glyptal.
