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.

Thanks for all the information and suggestions on pipe for a secondary
coil. Forgive me, I'm a perfectionist. I have decided to go with the white
schedule 40 PVC and to dry and seal it inside and out. If the price I get
from the Dolph Company is reasonable, I plan to use their ER-44
polyurethane coating. Here is Dolph's description:
Low cost, fast drying red polyurethane insulator. Excellent coverage and
protection. Oil and moisture resistant and excellent adhesion.
It also says that the dielectric strength is 2000 V per mil and AC-43 is
listed as 1800 V per mil.
It is listed under their insulator category and it comes in spray
cans,which I think will be easier to apply.
When Dolph gets back to me, I'll post the cost and any comments I get from
their rep as to suitability of the product for what I have planned.
