has recipes for every finish you could imagine.

I've heard that if you just take it outside and pee on it, then leave it out for a few days, you'll get what you're looking for. I have not verified this, nor do I plan to. You might try a mild vinegar solution then bake at 200 F several times.

As has been mentioned before, Incralac lacquer is the only thing to use on copper based metals, and it does work.

Automotive spray-can clear coat will work fine, as long as you allow it to dry well between coats, and lighty wet sand between coats.

Thanks, that's what I was looking for.

Darn...I was hoping for one of those "reflecto-porn" pics like you see on ebay.

Incralac has special chemical properties which preserve the finish. Might be overkill for indoor use but it drives me crazy when stuff oxadozes under the lacquer. Love hte patina info as an architect I've been searching for this.

My browser filter stuck this in the SPAM folder due to the title!

MantramAudio,

How do you deal with fingerprints? I've noticed that the non-anodized aluminum I've worked picks these up very easily. The glossier the finish, the more visible.

Peter, just to let you know, there exist a similar stuff to alodine but for copper. I was using it when I was working in a plating / anodizing shop....I just need to remember what was the name...It used very frequenly on microwave telecommunication equipment to protect from corrosion.

I will try to find the name of the stuff.

Dark Shadow,

You said you worked in a anodizing/plating shop and as we live in the same city I was hoping you could tell me some places I could go to anodize some parts for an amp at reasonable prices.

My parts are somehow small anyway, 2 6"x3"x0.5" plates



Also, there seems to be a reasonable amount of diyers in montreal and its growing more and more with the popularity of the GC, it somehow introduces people to sites like diyaudio.com. And once you make one project, you somehow get addicted to diy, and can never stop and you waste all your money in it. (speaking with experience)

Anyway, we could all one day organize something nice.

Sorry for being a little offtopic here...

I was working for CPTech at St-Kaurent city. So have this place or there have also TNM amd verdun anodizing. All will do anodize for small part but will changer a minimum cost I think like 75$. So you should try to get lot of part or make a group buy do get down the cost.

It would also be great to organise something to meet all diy of mtl.

Btw do you know any place in mtl that sell blackgate capacitor? I got all my sample from Nation to build my GC and the rectifier but I missing the transformer and more important, the capacitor...
