You can polish them with 'T-Cut' car paint restorer
It also works a treat on dulled car head lights.

LBA is good for you, a Lens a day helps you work, rest and play.
Unfortunately I seem to have left my set of three 100mm ND Grads on the side of a hill in the peak district somewhere... DOH!

Do any of you out there have a set of Hitech Filters? I do, the ND Grad 3 filter set, 0.3, 0.6 and 0.9 ND soft grads and very useful they are too. However, being made of resin, they are easily scratched / dulled, so you have to be careful with them and I have made the mistake of not being very careful with mine, e.g. storing them back-to-back in a pouch, with nothing between them, so they rub together and any minute dust particles effectively act like sandpaper on them.
I've found out tonight something very useful. You can polish them with 'T-Cut' car paint restorer, the type specially formulated for metallic paint, used on a damp microfibre cloth. As long as the cloth is clean, this doesn't leave scratches and restores the filters to a mirror like finish. It won't remove deep scratches, but it is effective otherwise.
Hope this is useful information for anyone with Hitech or other resin filters. BTW, it's important that the filters are coloured all the way through and not just surface coated, otherwise what I'm describing will most likely remove the coating.
