Hi Paul,

I second Jim's posting that nearly any CLEAR coating should work fine for 
Tesla coiling.  I have used clear poly, spray lacquer, and epoxy coatings 
on the secondary, with no problems.  Clear shipping tape also works.  The 
main purpose of coating the secondary coil is not so much as for 
insulation, but rather for mechanical protection of the 
windings.  Occasionally, thermal expansion and contraction will cause 
windings to slip and fall.

Coatings to avoid would include anything that would be remotely conductive, 
such as black barbecue paint, metallic paints containing silver and gold 
flecks, and probably latex (contains water until dry.)

Let us know how the clear enamel paint works for you.

Karl
