Sitech Handpad

[Horwig]

Have asked this on the mount section, but I'll ask here as well

I have a 10 year old Sitech system on my mount, the handpad conductive plastic keys are getting to be no longer conductive. The good one measure in the low tens of kohms, the bad one many hundreds of K.

Anybody have any experience with ageing conductive plastic? Would a good clean with a suitable solvent remove any surface effect? or would conductive paint make a lasting repair? Have tried surface abrasion, no difference.

Have asked on the Sitech forum as well

Many years ago my Meade hand controller had a similar problem. I bought a product from the USA that repaired it perfectly. It was a conductive rubber paint. I can't remember it's name. Try looking for it on line.

If it is a flexible rubber keypad have a look at this. https://m.youtube.com/watch?v=oQ8CsIp9bp0
