Works just fine. I have used a section of cling plastic food wrap
("saran wrap") placed over one open end of the tube. The wrap is
held in place with a rubber band. Pour about one cup of sealer
into the open end of the tube and rotate 360 degrees while
holding the tube at a slight angle. This should nicely coat the
inside of the coil form. Pour out the excess sealer.

This does nothing to improve the breakdown voltage of the
secondary coil construction. You still need end caps if the
secondary is intended for high performance operation.
