It would be cool to see this on a mod and matching RDA, as long as you could ensure that it does not get inside the RDA. I wonder how it would handle the heat from the hotter builds though. Probably fine.
Heat shouldn't be a problem as it can be used on gun barrels, which definitely got a lot hotter than any piece of a mod/RDA should. I figured as long as I can keep it only on the outside of the mod and only the outside of the RDA tube, it should be as safe as anything else. I think I'll be hitting up someone local to look into it.
