Plastic Spray Paint

Appearantly this is a discussed topic elsewhere so i have a question. I just spray painted my pvc pipes that are going to be in the tank. Is this safe? how long should i wait to put it in the tank if it is safe? wish i would have asked this earlier.

 

I used krylon paint and i hear other people have without problem. whats your take? some people even paint the pvc purple primer first and then black so when the black chips it will look like coralline

 

I know krylon fusion is reef safe once dry. I bet many other paints are as well, but knowing that the fusion is reef safe, I tend to stick with that.
