Hi Paul,

I bought a gallon of both Glyptal and AC-43 from Dr. R about 2 years ago. 
At that time AC-43 was about as expensive as Minwax Polyurathane at $25 a 
gal.  The Glyptal was another story at $78 a gal.  Prices have been going 
thru the roof for electrical chemicals lately, so don't be surprized at the 
prices.  I just paid $30 a 16oz can of Blue Shower replacement.  It was $10 
last time I bought it.
