CRC Rust Converter, 1 Gal

Works great and affordable! Put a shine on and did turn the rust black. Applied with a microfiber cloth with good results.

This stuff works!

Seemingly provides good coverage and a good seal but is not completely effective at converting the rust. I prepped my truck frame per the instructions and applied per the instructions where it worked it looks great where it didn't completely work you can still see an orange rusty frame. I would say the it worked on about 70% of everything I coated. If I remember to come back I will update with how well this holds up over the winter with salty roads.

This seems to work very well. Used this on the underside of my truck. Looks good, and as it doesn't gunk up everything, you can still turn a wrench under there. As this is a chemical reaction, and the label says temperature between 50-90F, I did wait until the weather warmed up to the mid 60's before applying. I cleaned off the surface rust with a scraper and wire brush. Sprayed the underside of my truck with a garden sprayer in two coats. it has turned all rusted surfaces black. Wear a mask, especially working under something. Cleanup is easy with just water. We'll see how it stands up to east-coast weather and salt.

How the hell did someone make rust not rust again ? Genius!
