Hi everybody!

Does anyone know which spray paint was used for the "laser speakers"? I am looking for exactly this type of paint for quite some time now but couldn't find it anywhere. It's nice to see that it actually exists.

So, if anybody knows the brand and paint name it'd be awesome if it was shared with me.

Hey! It was Rust oleum Aged Iron effect paint. Hope this helps!

Amazing! Thank you very much. Looks like it's hard to come by here in Germany. But I will keep looking. In worst case I have to import from the UK.

Thanks for your videos. Always fun to watch! 😊Ā

Edit: Found a seller on eBay! 😀Ā

EDIT: See the warning at the bottom of this post which I should have included: thanks to @madscientist for reminding me.

Awesome. I used Rustoleum on my 1:1 scale Proton Pack.

One trick I learned (and be careful with this) is that if you heat the can in some boiling water until it's just about too hot to hold (use a towel or some rags) and that thins the paint out so you get small aerosol particles and it's far easier to paint without all the sputtering that can happen when it's cold.

Water baths are safe and easy to use, but don't put it in a pan of boiling water as the pressure in the can could cause it to go pop and spatter paint all over the kitchen..

(Yes dear, I'll get around to cleaning it - after I get the bits of shrapnel out of my eyes.)

-----------

CAUTION:

As Mad Scientist below points out, butane propellant should not be heated beyond about 40C - which is too hot to hold but enough to touch quickly. Any hotter and it might go a bit "bangy".

Also don't (please don't) do this on a hob, especially a GAS hob. A water bath from a boiled kettle is quite sufficient, esp. if you spray outside (which is recommended if you don't have a fume extractor and/or a spray booth setup). The butane propellant is highly flammable and most solvents are organic (carbon, petrochemical inĀ  origin) and also ignite at surprisingly low temperatures. Not sufficient to cause a spontaneous ignition the temperature of superheated steam. As butane ignites at 400C or thereabouts,Ā  any naked flame could potentially cause an explosion resulting in injury.

While this is extremely unlikely, the last thing we need is for anyone to get hurt!

(And here's me shouting at other people on line for repairing high-voltage stuff without warnings to others...)

If you don't understand it, ASK someone who does.

Take everything I say with a pinch of salt, I might be wrong and it's a very *expensive* way to learn!

Thanks for the advice. Usually butane filled cans should not be heated above 40°C. I will try a ~40°C warm water bath and see how it works.

I'm a mad scientist too (well, a grumpy old science writer). šŸ™‚

IĀ  believe you are correct. I certainly wouldn't heat them to the point where the stuff was cooking. Although I might see if a pressure cooker could destroy one at 120C. I expect the pressure would prevent a pop during the heating stage but when the pressure release is opened that pressure drop might be enough to cause a rupture. But that's controlled conditions of course - an explosive can would not ignite in there and the steam would keep the oxygen levels below LEL (lower explosive limit) I expect.

I wish I'd known about LEL and UELs when I was a kid making fireworks in my parent's garage. Nearly set the place on fire more than once! WHOOPS.

40C is pretty hot for your hand anyway. Water is a great way to do this because you can gauge the heat more accurately (and no naked flames just in case). And if the worst happened and the can "exploded" it would be in the bath.

Hence I'll put caution on there for everyone just in case someone tried this on a gas stove!
