Reef-safe Paint for PVC

[Biokabe]

Back in the day, the go-to paint for anything reef-related was Krylon Fusion. It seemed to vanish for a while, but there's now Krylon Fusion All-in-One. Is this stuff still suitable for painting PVC, or is there something else that people are using these days? Assuming it's fully dried and cured, of course.

Mostly what I don't want is chipping and peeling from in-sump humidity. Bonus points if it can survive submerged without, but if we don't trust submerged applications I can just leave the plumbing unpainted for any parts that will actually be submerged.

Except that colored PVC is multiple times as expensive as plain old white PVC, even including the cost of a can of spray paint.

I'm trying to find cost savings where I can, I'm already spending money I didn't want to spend.

Here’s a funny idea… black ASI aquarium silicone?

It’s guaranteed reef safe… though, application would be more than a bit messy! (much less achieving a smooth surface finish!)

Yes and no.

So Krylon all in one works great and also Rust-Oleum also makes one for plastic/pvc. The problem is when you say “submerged.” Now you’d be talking a pool/pond paint. These are brush and roll applications. With pool/pond products you’d have to use an alcohol based primer and then the pool/pond paint. Of course this option is getting into big money and doesn’t seem to be a cost saving option. The Krylon & Rust-Oleum is your best bet but longevity would be my concern…
Like others, I would say use black pvc for the submerged sections. For stuff that is out of the water, I’d think either of those two products would work well.
If it were me though, knowing this is a setup that’s gonna be there for years and maybe decades, I’d spend the extra for colored pvc. Myself I just use white… it’s under the tank in my setup.
Best of luck.

Yes and no.

Thanks.

I'm fine with leaving submerged portions unpainted if not 100% certain that it's safe. If all the plumbing were going to be completely in the stand I'd also be fine just leaving it unpainted, but it's an external overflow with external returns, so at least some of the plumbing will be visible.

Guys, the original Krylon spray paints were totally reef safe, and you could submerge the parts without a problem. I'd also be interested in knowing if any other spray paints would also be safe like Krylon was.

I have used PVC to make a frame for my screen lids to keep the paint and metal of the normal frame from being destroyed , could I use that product on that ?
