I'm currently working on a handful of high voltage projects, and I'm stalling out trying to insulate. Any suggestions for an easily obtained and relatively in expensive epoxy for insulating high voltage?

 

yep, http://www.mgchemicals.com/products/epoxies.html

available at most electronics distributors. i think i get mine at Allied Electronics http://www.alliedelec.com/

 

Would there be any usable epoxies at the hardware store?

 

They are not rated for insulation properties.

There is also a substance called "corona dope", if you can still find it.

 

if possible, you could melt some glass around whatever it is you are insulating. this would be cheap.
