As for your alloy question, yes. The alloy specification itself is just the grade of aluminum used. Similar to the way you would find the type of steel used to make a knife or similar things like that. As for what type of spray paint to use, I would recommend a Rustolium metal paint. Go to your local hardware store/paint store and ask them for a specific ...
It is a very minor dent but horizontal mid tube is not a good spot. Creasing a tube does reduce the strength. A hard landing or hard bump is where that would likely be the first point of failure. Even if that section has lost 50% strength it would take a lot for the bike to fail. The rest of the frame is there and even 50% strength on that section is a lot ...
I'd say that's fine to ride. Seems like got created by applying distributed pressure over a pretty big area. Therefore no chipped paint etc. Even if that cracks apart, I wouldn't expect the entire bike to fall apart immediately, you still have the lower tube supporting stuff together:)
Just off the picture I'd say it's fine. Aluminum is more durable than many people think (you know they build airplanes out of the stuff?!) That said, I would carefully look at the areas where the tubes are welded together. Use a bright light and look for any small, hairline cracks in the paint. Most of the aluminum bikes I've seen fail usually snap at the ...
Don't ride that. Aluminum will randomly snap at the best of times, and a fold-looking bend like yours only makes it worse.
