That particular picture was simply 3 ounces of 1F powder, cardboard wad, and a $100 point and shoot camera. It was the second time I ever shot the gun. The first time, a half hour prior, I was hiding behind my house having no idea what would happen. I do wish all my backyard "junk" wasn't in the background of the picture.
POR-15 (
www.por15.com ) is a urethane paint system. It sticks like you would not believe. It stays a bit flexible so it won't crack as temperatures change. From a practical point of view, unless you own a paint shop it has to be brushed on, not sprayed. I flows nicely however, so you won't get any brush marks when you are done.
To use -
First remove existing paint. Paint stripper would be best bet.
Wash well (soap water, rinse) to remove paint stripper.
Let dry completely. If there is thin surface rust, leave it there. Don't take it off. It works better with rust. POR = "Paint Over Rust". If after you wash it, the barrel is nice and shiny and rust free, wait a week and let a thin rust film start to appear. Light rust is good with this stuff. It give the paint something better to stick to.
Brush on the phospate primer, let dry.
Brush on clear POR-15, which is a one part moisture cure coating. I would use 2 coats. Let dry.
Spray with POR-15 Tie-coat adhesion promoter.
Brush on 2 coats of the two part "Top coat" in the color of your choice (black?). Let dry for 4-5 days.
Done.
It will not come off as far as I know. If you get it on you it is on you untill you grow new skin.
The whole deal is sort of expensive. You will spend close to $100 bucks on the entire kit, but in the end it will be worth it.
A tip, the base coat comes in several size cans. Get a few of the small cans rather than one big one. THat way when the can is empty you just toss it. If you use half a big can of it and you try to reseal it, getting the cover off is next to impossible. You can put saran wrap between teh cover and the lid, but it doesn't seal well and won't tolerate long term storage. Way better to use small cans and toss them when they are empty.
Also, when you mix up the 2 part top coat, use a metal can to mix it in. It will eat thru a plastic cup in about 10 minutes, You can buy the top coat in a bigger can because it won't set up untill you mix it. Just mix the amount you think you need in a separate container.
Careful though...
Avoid breathing the stuff. Don't work with it in a confined area. Don't spray it unless you have appropriate fresh air respirator. It cures by absorbing moisture. If you breathe too much in, it will cure on your lungs (which are moist) and kill you by suffocation. There is no solvent in it, so it isn't going to evaporate for you to breathe in if you brush it on. If you spray it on though it will go into the air as a mist and you will breath it in of you aren't properly set up.
The POR15 web site tells much more about it than I just did,
