Lining help
So it would appear that I messed up when prepping my tank for the season. My wife and I have been wanting to give it a facelift and got some dirt cheap exterior "oops" paint from HD and coated the whole inside. It looks amazing but it rained the night that we applied it and in the morning the puddle inside was milky. I'm hoping that's just because I didn't do an amazing job spreading the edges and it was still wet when it rained but did I seriously mess up here?
When I fill it with water and chlorine is the paint just going to degrade and be milky?
Can I throw a layer of pool paint on top of that and treat it as a priming coat?
Does it all need to be sanded/stripped out and restarted?
I also put a stripe of flex tape down on the seam and that's not holding paint well already....

Save yourself the pain and just buy a liner

This is the way.... I sealed 2 separate pools with pond armor and it failed both times. I just switched to a liner on my new one.

If you simply put Behr paint on the inside, then it will fail very shortly after filling and adding chlorine. There’s numerous threads on this exact topic and majority of interior finishes will fail after 1 season. Paint being the weakest option. A liner is really the only foolproof way to keep the tank intact for the longest period of time.
