spinoff: rust preventative paint on concrete

[budget76]

the rust bullet thread reminded me. i'm sure the answer is no:

has anyone seen the results of painting concrete with a rustproofing paint like Rustoleum/POR15/etc? I know it's a dumb thought. but i've had spots on the floor that don't look like they're ever going to wear away, like they somewhat absorbed into the concrete. maybe solvent spills would kill it?

I won't be the guinea pig. but i'm curious if anyone's seen it. Knowing my parents had moderate success in the past with normal house paint on the floor of their garage (except hot tire spots), and that rustoleum is way tougher than that paint, I'd be surprised if nobody's ever tried it

One of the vendors here has a product like POR. Check out https://www.garageflooringllc.com/product/trualloy-kits/

I unintentionally dripped some POR15 on concrete and it started to foam a little. I was thinking it was intended for etching metal, so I was thinking that it was slightly acidic, and thought that's probably not good for it.

Someone much smarter than I will chime in a more reasoned response.

One question that comes to mind is, at over $200 per gal for POR15 why risk it? You can get purposely designed epoxies and sealers for less.

If you want to coat a floor with residual petroleum products in it we carr our Oil Stop Primer which will adhere, then coat with one of our epoxy systems.

i wouldn't. but at $50/gallon for rustoleum, I figured someone out there had tried it out
