Can anyone recommend the best clear coat, high-gloss (or Satin when needed), non-yellowing sealant for metal? I rather buy it in quarts / gallons to apply with brush or foam pad ... But if you only know of a spray, then I would welcome any advice / recommendations. The sealant will be used for all types of metals (Copper, AL, SS, etc.)

Permalac from Peacock Labs has worked well for my work. It can be purchased as a liquid or in a spray can. I'm not sure how well it will work with foam pad or brush. Dilute with Xylene.
McMaster-Carr (www.mcmaster-carr.com) carries a 3 part clear epoxy that is used on Ocean Liners. It can be sprayed or applied with a roller. You may be able to apply with a foam pad. I have used this product 2 times and it has held up well and is extremely hard. It is like an automotive clear coat on steroids.
Both products require ventilation and a respirator. Spraying with a gun and compressed air will give you the best results. After a few days of cure time, treat the surface with medium scotchbrite, 2000 grit sand paper for auto finishing or 0000 steel wool will give you a matte surface. Follow the abrasive with a wax for a satin finish.
I'm not sure how well these products will work on aluminum.
Permalac (which glass attack recommended) also comes in a satin finish. Peacock Labs recommends that you appy gloss finish Permalac first, then the satin over it. It comes in an aerosol can, and quarts and gallons. Not cheap, though. About $62 a gallon if you buy direct from Peacock Labs and they charge quite a lot for shipping if you want their metal cleaner and thinner too - $55 for a four gallon box - because they UPS it as hazardous material. If you get it through Sculpt Nouveau, you'll save.
