Hello David,

I too would fight shy of bakelite polish for a clear acrylic window, expecting its abrasive effect to be too coarse, and I've never actually met any T-Cut, but after your post I thought I should make quite sure that my memory of using Silvo in such an instance isn't a false one. So here's the central part of an RT1 dial after ten minutes' vigorous polishing of the perspex cover: I've only refrained from including a "before" image because it wasn't sufficiently different, as I expect the set received a similar treatment way back when and hasn't had any rough usage since.

Fine scratches are dealt with, deeper ones may not be helped much or at all, but I really don't think that polishing with liquid Silvo on a soft cloth runs any risk of making matters worse, at least provided the formulation hasn't changed dramatically since I bought my litre can of it donkey's years ago. If it doesn't produce a sufficient improvement the option of making a new window of course remains.
