Yep, you can definitely paint over Corroseal. It's a pretty common question among those dealing with rust on metal surfaces.
Corroseal is designed as a rust converter and metal primer, so it's meant to get rusted surfaces ready for paint. Basically, it turns rust into a more stable material, so it's not just sitting there eating away at your metal. According to the manufacturer, this whole process makes it easier to paint over once it's done its thing.
From what we've gathered, a lot of folks have had good experiences with Corroseal, especially when they prepped the surface properly first—like cleaning, scraping off loose rust, and making sure there’s no dirt or oil lingering around. One example we came across was someone who restored an old military jeep, and it worked great for them as long as they put in the prep work.
But not everyone has had smooth sailing. Some have mentioned rust coming back or peeling after some months, often linked to not prepping enough or not applying it thoroughly. Also, Corroseal advises using a topcoat as a follow-up. Skipping this could mean the protection doesn’t last as long as you’d like.
In more challenging environments, with lots of moisture or temperature swings, Corroseal might need that extra layer of a good topcoat to hold up.
To get the best results, be sure to follow all the steps: clean and prep your surface well, apply the correct thickness, and definitely go for the topcoat. It might need some maintenance down the road, but starting right maximizes your chances for success.
So yes, paint away after using Corroseal! Just keep in mind that the prep and follow-up really do make a difference.
