well, we have two experts in vaccum metalizing saying conflicting reports - 1 says it can be done, and the other saying it wont work at all...so of course, I am hoping it can be done. I dont know the costs to have it done over in your part of the world, but its about $40 each here if they would have done it...but I really dont know how one would come out until we do one.
like all items that get vacu-metalized, the surface has to be perfect, and devoid of any blemishes, because when you vacu-metalize something, if there are any imperfections, you'll see them, so prep work might be needed or its a waste of time.
Chrome dipping may allow for a better finish and more forgiving if your item has any blemishes, but costs more...so this is all speculation until one can get done.
