Who are folks using these days for re-coating?

The coatings on my RayCraft mirror failed... horribly...

Looking for longevity this time 'round.

Any suggestions?

Thanks,
Kerry

Up your way you might look at Clausing in Chicago (Skokie). I've had several mirrors coated there over the years, most recently my 16.5". I've had both Beral and aluminum coatings done by them and both have held up very well.

John,

Yes, they're one of the coaters I was considering, mostly because they're local(ish).

A friend of mine and I were on a bit of a run making mirrors a few years ago. We took over two dozen mirrors of all sizes to Clausings. Every coating was perfect, almost all were standard Beral, a few were Diamondbrite.

Regards,
Don

I remember Clausing from the 1980's, used to see there ad in the back of S&T all the time. I was just the other day wondering if Clausing was still in business or not. Thanks for the info.. :)

I've got an e-mail out to Cluasing. We'll see what they say-- not sure if they still service the amateur community still or not. Hard to tell from their website, which hasn't been updated since 2010...

I've also got an email out to Spectrum-- their website regarding their method and adhesion of the coatings is persuasive, though I confess I'm not sure how much of a difference it really makes...

You could also call Majestic Coatings in NJ. They do excellent work and provide fast service.

Jim,

Ahhh. Good suggestion, thanks! I didn't even know about them, so I'll check them out!
