Re: Preparing Al sheets; other factors
Just for the record:
After coating with 'the beer method' and drying, there is a faint
white powdery layer on the surface.
Just rinsing with water under the tap to get rid of it, let it dry ,
and it is the aluminum surface again.

I just used it as written; the beer was pilsener , a 6 percent german beer.Ok, pilsener is fine :) Will do exactly as it is written...Thanks, so the surface isn't white as shown in the reproductions inJust another thing: the reason i tried aluminum was the 'silvery shining', so in order to avoid the sanding -lost of shining- i used the toothpaste, in a way a 'pumice' or? The other thing is that for me the real 'silver shine' was obtained with 'kitchen aluminum' (i mean the stuff used in the kitchen to wrap things :-). succes,
