Sort of depends on what you ask, when you ask it and who is looking at the posts. Sometimes helpful, sometimes not, but it is free.
Is that a type of paint or a brand name, I am unfamiliar with it.
For the most part you are not going to be heating up the cage so drastically that I would expect a finish of any sort to bake out.
I use semi gloss latex paint on the interior of my cages. It comes in any color, is cheap and easy to apply. Exterior surfaces and all surfaces (including the interior one) of front fascades are stained and finished with marine varnish. I use varnish because I like the look and dislike the plastic appearance of urethanes. It takes about a week for the finishes to fully cure and lose the smell, after that they are ready for animals. Built and used cages like this for years w/o any problem.
