I sealed the edges of the faceplate/CRT with aquarium-grade clear RTV. This was outside the field of view permitted by the housing of my HP terminal. Keep everything absolutely clean (I used acetone) so that no dirt or smudges will be permanently trapped between the two surfaces. Use good lighting, outdoors (because of the acetone). I would STRONGLY advise ALWAYS replacing this faceplate. I'm sure that having it in front of the CRT itself will be very helpful if there is an implosion. I have read that the neck a a CRT tends to be shot through the front of a CRT in the event of implosion. This would be bad. Once assembled this way, there has been no optical affect whatsoever visible on my CRT. It is impossible to tell that there is a space between the CRT and faceplate (in my case, around 1/4-1/8". -Steve Loboyko Website: http://juliepalooza.8m.com/sl Nixie Watch (one-tube):http://juliepalooza.8m.com/sl/complwatch.htm __________________________________________________ Do You Yahoo!?
