Summary for dacromet sunlight exposure Discussion
Dacromet sunlight and outdoor exposure are the main concern in this thread, where Sergio Yamazaki asks how Dacromet 320 on springs holds up to sun, rain, and snow. Olivier Bost replies that, as far as he knows, Dacromet has a clear gray, aluminum-like appearance that does not change with sunlight, including the black version sold as Dacrokote. He adds that exposure to water may darken the coating slightly, but it should remain in the clear to medium clear gray range. The exchange suggests the finish is generally stable outdoors in appearance, though it may shift a bit when wet. No contrary experience is given in the excerpt.
Q. I would like to know what is the experience of Dacromet coatings used exposed to outdoor, like sun light, rain, snow etc
I am using dacromet 320 in springs, used in outdoors.

A. Dacromet is a registered trademark of Metal Coatings International. Your best chance for finding information on this coating is to ask the vendor directly. Vendors are usually very knowledgable about things like this.
I do not have direct experience with Dacromet, so I can only refer you to the company. I can tell you that Dacromet is used in cars (somewhere), so it has some amount of weatherability.

A. Dear Sergio
Dacromet is a clear gray coat, with a look of aluminium. As far as I know, its aspect doesn’t change with sun, including the black finishing Dacromet called Dacrokote. Its reaction to water will be to darken a little bit, but it will still be from clear to medium clear gray.
