Dwight,

Too cool!! Looks great. Glad the my heat gun method worked!

Just as a note to those who try the heat gun method. works wonderful on the rca tubes, or any tube with the white dryed out look on the edges. The PVA is slightly different from the zenith tubes. Basically, if you have green halo, do not attempt to use the heat gun technique as you will destroy the lens, it will crack, as you heat it up. The pva is extremely thin twards the center on the zenith crts (almost as thin as a sheet of construction paper!), so when an air pocket is created...CRACK!, you have sucessfully destroyed the lens. the lens will also crack if you try from the edge. Even a heat lamp will ruin it. Unfortunatly I am speaking from exerience. I guess you dont find out untill you try. The PVA on the green halo does not dry out like the rcas, it maintains is resilence and is sticky and slimy compared to the rca pva which is dry and does not have that much adhesive characteristics to it, thats why it works so well with heat, it will produce an air pocket and pop off with a bit of wedged pressure from the edge. Zenith pva is a total pain to remove, it takes forever and comes off; in bits and peices and tears off every fingertip of the way and leaves a bad residue that nothing will remove. Ive used WD-40 grease removers, basically scrubbing the lens with an abrasive sponge works the best using simple green. Even that is a pain and takes too long. Here is my advise, DONT TOUCH GREEN HALO (unless you use the hot wire technique which works excellent as I found out after some experimentation) But remember, you will still have to remove the pva from the face of the crt!
Have fun!!!
