Urauloth Posted April 19, 2023 Share Posted April 19, 2023 World's slowest hobbyist question. My most recent spray undercoats are from May '21 (one Citadel, one Army Painter). I haven't had occasion to spray anything since that year, and I don't have a lot of experience with how these things age, since back in the day I'd use them up fast undercoating a ton of stuff at once. Are these still good to go if I shake them enough, or do they go off if they sit on your shelf for 2 years? Should I be picking up a new one before I start undercoating?

andes Posted April 19, 2023 Share Posted April 19, 2023 Maybe test on some old sprue? Link to comment https://bolterandchainsword.com/topic/378368-how-long-do-rattlecans-stay-good-for/#findComment-5936641 Share on other sites More sharing options...
WrathOfTheLion Posted April 19, 2023 Share Posted April 19, 2023 I'm pretty sure I've used ones more than two years old before, I'd just make sure to shake them up well, and maybe test on something as andes mentioned.

Urauloth Posted April 19, 2023 Author Share Posted April 19, 2023 For sure, I'd never try it on a model without testing it first! Just wondering what to expect. If it should be good, I'll give it a shot. Cheers!

Grotsmasha Posted April 19, 2023 Share Posted April 19, 2023 At least 6 or 7 yrs, but not 15.....I've just discovered my Mournfang Brown spray quite chunky BUT I did buy it BEFORE this current paint range refresh....

Firedrake Cordova Posted April 19, 2023 Share Posted April 19, 2023 (edited) Personally, I'd just try it on some spare sprue if you were in any way worried. I had a can of the old GW matte/satin varnish that was fine 10 years after it was purchased in the mid 1990's...

Cleon Posted April 21, 2023 Share Posted April 21, 2023 Also depending on where you've been storing them (a cold garage for example), it might be worth letting them soak in a warm water bath (comfortable hand temp - nozzles above the water) before you shake them, to let it warm through first.

Firedrake Cordova Posted April 21, 2023 Share Posted April 21, 2023 It's probably also worth checking the nozzle isn't clogged from previous use.

Volgon Posted April 22, 2023 Share Posted April 22, 2023 (edited) Testing the rattlecans on something low value as others have said is definitely the best advice you can get. That being said, my anecdotal advice is that this week I used 3 rattlecans (1 Krylon, 2 unknown brand if it matters) that had been stored in a cool, dry closet since around ~2014 and they seemed to work just fine. I don't necessarily expect that to be the norm, so again, testing is definitely in your best interest!

Bash Posted April 28, 2023 Share Posted April 28, 2023 I actually was curious of this myself as I recently dug through an old closet and found a black rattlecan. Gotta be at least 5 years old, glad to hear it's still probably good but I'll test it when I need to use it.
