Best thing I've found for silver is regular old-fashioned incandescent lights, used in an otherwise dark shop.
The halogens are good to work under, but I turn them out and use incandescents for the final inspections.
The various "sun guns"/Xenons never work all that well for me...I don't see marring that I *know* is there. Plain bare bulb incandescent fixtures show stuff that I simply can't see under any other lighting conditions.
There are some threads where we discussed this in depth..but the short version is that only by inspecting under incandescents (from different angles and distances), in a dark shop, can I see *everything* on silver and thus avoid unpleasant surprises under unusual lighting conditions at night.
It's a matter of "distant point-source illumination". Not just a matter of brightness or color, but also (and more importantly) a certain specific type of contrast that makes stuff like swirls stand out.
Bare bulb ceiling mounted fixtures work best for me, followed by shaded ones that hang from the ceiling, closely followed by a hand-held incandescent work light. Since the two best ones require wiring the garage for them, I'd just get the hand-held. My Lowes has them in a high-wattage version; I use ~300w bulbs in mine.
