Aquarium safe paint?

Hi Fishy, I'm kinda interested in your filter. Did you use threaded PVC or just cement the endcaps on?
 
Just make sure to let it cure at least 24 hours. I had a few spray bars that I only let them dry to the touch, and the paint chipped off. I think this stuff needs a little extra time to really bond well with the surface. Things I've painted and let sit for a few days before putting them in, the paint generally seems to hold up a lot better.
