I've got the trap lately of restoring pens. However I've got a few pens that need a bit further work to improve there appearance. In the worst cases I've used upper grades of micromesh followed by Polywatch a product which is usually used to improve the appearance of watch crystals. This method gives a decent level of improvement however I was wondering if there are better options out there. I'm hoping for something that I would at least be able to find on line in the UK
