## Product: FDC Rust Converter Ultra
**Brand:** FDC

If you're planning to use FDC Rust Converter Ultra, it's good to know that one gallon can cover up to 500 square feet, as long as it's applied to a smooth and non-porous surface. This makes it a pretty cost-effective choice, especially if you're dealing with a bigger area or need to do multiple coats.

A key thing to keep in mind is prepping your surface properly. According to how the manufacturer describes it, you'll want to remove any loose rust using a [wire brush](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dwire%2Bbrush%26tag%3Dssw.ans.tx-1-20) or [sandpaper](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dsandpaper%26tag%3Dssw.ans.tx-1-20). 

Doing this will help the rust converter stick better. Once prepped, you can apply it directly using a [brush](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dbrush%26tag%3Dssw.ans.tx-1-20), [roller](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Droller%26tag%3Dssw.ans.tx-1-20), or [spray](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dspray%26tag%3Dssw.ans.tx-1-20). No need to dilute it.

Don't forget to let it cure for about 48 hours before deciding on a second coat or adding paint. Depending on how rusty the surface is, a second application might be a good idea. 

The prep work and following these steps really make a difference in how well it works. Our research indicates that results can vary, and the secret to success seems to be in the prep work. Many who've used it say surface prep is crucial, as is paying attention to storage and application temperatures to avoid issues.

Overall, if you follow the guidelines, the FDC Rust Converter Ultra could be a great option for transforming rusty surfaces into something you can paint over and protect.
