    I am making some stuff that is going to live in a nasty environment - It will be exposed to both hydrochloric acid as well as chlorine gas. Nasty stuff. Even stainless steel rusts in this environment. So I'm looking for a paint that will survive. Anyone know of anything made for this? Preferably an aerosol.

    Teflon paint. Brownell's gun coat stuff. You clean the metal, paint it on (aerosol), bake it, done. Teflon finish like a frying pan.

    Automotive undercoating or foundation (tar) paint.

    They do make paint for this environment, it is expensive though. Check aviation paint for starters, the kind for inside compartments and structures.

    How about some of that garage floor epoxy paint?

    We have used that in the past for this environment, and it works. Kinda looks like hell though given that it is applied with a brush / roller.

    Apparently there are some powder coating powders that can handle it as well.

    ^Powdercoating is what we do for our Navy stuff.

    But then heat/salt water are what it gets exposed to, not corrosive acids/gas.

    Imron is about the toughest paint I have seen. Real nasty stuff, but I was talking to somebody today who said that they spilled brake fluid on a frame painted with Imron and let it sit for 3 days without noticing it. No damage. J

    The best stuff for the job is what they recoat the cast iron tubs with.Its a two part epoxy that can be sprayed on for a great looking finish and its cheap and sold in most DIY stores(lots of colors to choose from too).It will hold up for years in that environment.Powder coats are useless without a great powder primer which most people dont use and the cost is crazy high. Hope this helps.

    See if POR15 has something that'll work. Their Hardnose lines are designed for harsh environments.

    Don't get any of these coatings on anything you don't want painted. Like the inside of your lungs or your eyeballs. Some of these chemicals can deactivate the former and polymerize the latter.

    Check with a plating equipment supplier. Thier stuff is designed to work in just about the chemically harshest environment around.

    What kind of plating? Chlorine gas attacks all of the platings I could think of.

    Hmm - maybe nickle. Didn't check on that one.

    Nickle should do it. I remember reading about Chrysler doing nickle and possibly chrome plating for some kind of chemical lines or something for the US government during WWII.
