I bought a few bottles of Ammo of Mig paint that have cracked tips, so every time I shake them, the paint spills into the cap and gets wasted. Is there someplace where I can buy these tips, or the whole bottles?

You could screw the cap down, over a piece of plastic wrap.

Or you try to contact Ammo and ask them or some retailers on Aliexpress,e-bay etc...But there is the problem of size, is not easy to find the right one i think.

Or the third option is to change the whole bottle, even here you find it new on Aliexpress or e-bay but quality is always in doubt or from a US producer where you pay a bit more but you have the quality.

Thanks guys--I did a bit of searching and found the bottles for about 60 cents each, shipped, so I got 5. We'll see if they work.
