Firstly, thanks Vleisman for the info about the AMT shop. That should answer another question posted here. My costs were high, but convenient as I could get everything close by.
I only used the products in the pics with nothing added to the resin mix. I believe that you can get clear resin where you can add pigment, but Herbert Evans only had the one which drys white.
I did do a small test sample with some matt black model paint, but it came out grey. It would surely work with clear resin though.

This pic is the slider knob with 6 fine coats of matt black. I will attempt the thin red stripe this week sometime.
Plascon Aerolak works well here and doesn't scratch off. I tested it on the small sample I made.

Epoxy putty to fix the parts where the air pockets were, and bubbles. Normal Pratley stuff here.
Sanded down and ready for paint.

Handles almost done. The original is middle top, and also getting a touch up.

Cool, man! From the settings, looks like you didn't need a graphic, after all!

It's still in the workshop waiting for its ears  ;D
Not really a graphic fan, but it will look cool stacked with the other components.

Lovely stuff! Excellent outcome. School fees are quite high and making small quantities of something is expensive. You should have made 5 more of each slider sold for R250 on ebay to recover the outlay ;)

Thanks for the positive feedback. I do have 7 more sliders waiting in the wings. I have only painted 2 though. It's on 125Hz BTW.
It's reasonably easy to make more now, so I will post exact dimensions tomorrow and these items could possibly be used for other brands too.

Done !.
Cover resprayed, front panel touch ups done, LED to replace the blown power lamp sorted and the rack handles fitted.
Next will be cover resprays on the other components, and touch ups where needed.
