Isn't the red stuff permanent locktite like stuff? Of do you think it is the less permanent blue locktite, except red in color?
If permanent locktite stuff, you have to heat the screw until it is very very hot, like getting near red hot, in order to break down the permanent red locktite.

The small or tiny chisel or punch method works. You might be able to carefully drill a small hole in the center of the screw, then tap in a small allen wrench and unscrew it. If you have a small reverse drill bit, you can carefully start drilling the center of the screw, and usually, the screw will unscrew itself in the process. If the screw is sticking up slightly, you can sometimes use a dremel wire cutting disk and cut a small slot in the screw for a jeweler's screwdriver. Sometimes the chisel or punch works to cut a small slot enough for a screw driver to catch and unscrew the screw too.
