Powder coating ammo cans?

Was thinking of powder coating some fat 50 ammo cans, but realized the oven temp is probably going to burn up the gaskets.

Any one ever successfully removed and reinstalled the gaskets on ammo cans? Any tips or advice?

DRE used to sell powder coated cans so it must be possible. FWIW

The gaskets are easy to pull.

The gaskets are easy to pull out. Being a cheapy, I have not powder coated mine however, I have welded steel loops on mine and painted them. The steel loops to make them easier to tie in but have easy access to opening them. The loops are closer to the bottom of the whamo cans. You know, fishing gear and such.

I've got a home powder coating kit from Eastwood. They work great and anything that will fit in your oven can be coated with professional results. Whatever you coat has to be sand blasted completely removing ANY paint and the oven temp is generally about 425 so yes you need to remove the gaskets. Quite a bit of work but they would look great and more durable than paint. Powder coating is not bomb proof though and will scratch and wear through in time. Not worth the trouble for me but each to his own

I use a "paint system" that is arguably as strong as powder coating and much easier to apply, plus requires no sand blasting.

Buy commercial Rustoleum/Krylon/ACE/Sherwin-Williams enamel in a quart or gallon can. $10/qt or $20/gal

Naphtha $8/qt or $25/gal

Alkyd Acrylic Enamel Hardener from the auto body supply shop. A pint usually runs $16

Mix 8 parts paint, 2 parts naphtha, 1 part hardener. It should be about the same consistency as whole milk. Brush or roll it on. It should be thin enough to flow evenly, but not so thin it sags/runs. I've had the best finishes by applying one very thin coat to wet the substrate, then flow over a wet coat about 10min later when the first coat flashes/tacks up.

You can also use a $16 Harbor Freight sprayer to apply it.

If you have bare or rusty metal, use POR-15 primer. If it's previously painted, hit it with 250-grit sandpaper or a 3M pad.

The addition of the hardener catalyzes the paint, and makes it dry about 5x as fast as paint alone, plus it makes the finish much harder and as scratch-resistant as powder coating. It's also a million times easier to touch up than powder coating. The naphtha helps thin the paint so it flows better and smooths out; it also helps the paint dry faster.

Have you priced out the powder coating?

I'd be interested to know what kind of quotes you've gotten. Seems like a ~$50 job for blast and coating, which I would guess is a pretty good deal compared to other quality options, including DIY.

I have had all of my cans powder coated. Mostly for looks / vanity but it sure helps prevent rust. Gaskets on rocket boxes are very easy to remove / reinstall and while you are at it a good time to 303 that bad boy. What I found a PIA was removing the handle sleeves and putting them back on without effing them up.

We powder coated our primary groover rocket box about 20 years ago. Things just slide out easier when it's time to dump.
