Cleaning an SCT primary mirror

you're absolutely right, it's all very unsafe.
Make sure you wear a protective mask so you dont inhale the paint fumes while spraying. :smashpc:

Personally, my favourite for scratches on mirrors is Dior Silver Pearl Nail Polish - no fumes, no overspray and you can remove it later with neat acetone. MaxFactor is a bit cheaper but doesn't flow as well. One final advantage is that it you put it on a bit thick, a light rub with 300 emery paper brings it up a treat.

For scratches on lenses or corrector plates, just get the clear version. Bingo!

One final top tip - if you're mirror finally succombs and is no longer usable, don't throw it away - use it as a shaving mirror. As an added plus for SCT's, pop a halogen bulb into the central hole and hey presto - you zits will stick out a mile and will be much easier to squeeze. Great if you have teenagers.

I have to say this is my favourite "tip" :rock: read it in an email and had to come on to giggle some more.

Just reading over this thread again and without even going outside you would know that we have no clear skies.

Stir crazies :woohoo:
