pasley:There has to be a benefit to the public for the government to pass a law and the related expenses of enforcement.
MikeC:Melvin, you live in the United States, the state of California.... PLEASE rethink that statement. There are some stupid laws on the books.

ChrisA:Let's assume there IS such a stpid law that you can't return a tank
or a reg. Ask the guy if his "law" applies to rental equipment and if
not why not
Yes, we have some weird laws, particularly here in CA. But they are enacted to benefit some segment of the public, be it tree huggers, or large campaign contributers. The law may have made perfect sense at the time it was passed, and be so out of place today (some laws regarding cars when they first came out and the horse was the dominant transportation are still on the books.).MikeC:Melvin, you live in the United States, the state of California....

jbd:From what I can find out it would have to be around 450 C to soften the aluminum enough to allow extrusion. Most baking systems, at least for automotive finishes are apparently done at 500 F which is about 260 C although there are some paint systems that use a temp around 1200 F which would be close to the melting point of aluminum. There are air dry paints that might work but from what I understand bonding of the paint to the aluminum is a problem. Some of the finishes I have seen on many scuba tanks leads me to believe that they are baked on by the manufacturer.
