Your dial looks fine Paul.

Re Xeropol, here's what the supplier says about how to apply it and how it works:

Quote:

How is the Perspex polish applied?

Clean the surface and apply a little polishing paste. Using a soft, clean cotton cloth or pad, polish the scratched areas using heavy pressure for 2-3 minutes. For deeper scratches repeat application several times. Remove residue with a cloth. Very deep scratches should be treated beforehand with the special super-fine (granularity: 1600) abrasive paper and a little water, then treated as above.

Do not use on printed, varnished or coated surfaces. Not suitable for polycarbonate or other materials. If in doubt, or for further advice - please contact us.

How does Perspex polish work?

The Perspex surface is lightly dissolved and polished with fine abrasive particles. During polishing, the edges of the scratches are rounded off and the fissure bottom is filled in. This returns the Perspex acrylic surface to its former smooth and shining glory.
