Hey diy I have a problem. I bought a can of acrylic paint 18 months ago, with which I painted my radiators (the paint was a matte brown color).
Today I decided to go over my radiators again with the same paint, but to my horror the paint turns out to be glossy as fuck now. I made sure to flip all my cans of paint upside down every months or so, and I've stirred in it quite a lot, so that can't be the problem.
Does this shit age or something? Did I do something wrong? I can go out and buy another can (probably), but it the color keeps changing, the problem will come back in a year or so.
Pic related, you can clearly see the difference between the two. Also, it's not a drying up issue

you know the more layers of paint you add to these, over the years it will decrease its efficiency because the layers of paint will start acting as insulation and not transfer the heat

1. Yes spray paint can go bad.
2. The pigments in most paints are in fact temperature and light reactive; oxidation, light and heat will change the color over time. Fact.
3. There is specialty "High Temp" paint made just for Radiators.
4. While layers of paint will reduce the radiators efficiency, I don't think spray paint will have an appreciable effect.

>to my horror
That's a bit of an exaggeration, don't you think? How serious is a glossy radiator?
