What paint for INSIDE overflow?

[banditpowdercoat]

OK, I normally wouldnt paint on a wetted surface of the tank. Allways paint on the outside. BUT, in the 150, were doing a V style coast to coast overflow. If I just paint the outside of the tank, you will see the V inside. I am wanting to paint the inside of the V as well, so that it blends in with the back. Is there any Reef Safe paint, or a sealer to seal the paint?
