My son inherited a 75 Chevy 1/2 truck from a distant relative. Do not know if it was a Calif truck all its life. It is a beater. Pulled up the rubber floor mats and found lots of rust. This is going to be a daily driver. My son and truck are in Mckinney Texas now. He doesn't have the money at this time to pay for new patch panels and does not have the equipment to do it himself. I have only seen pictures but feel the floor is reasonably solid. Might have a couple holes. Besides removing as much rust as possible what coating could be applied to minimize or stop the rust. In Calif we had a product that was labeled as a rust converter. It turned rust to a black coating. I do not know how well this worked. I'm sure if there is something in Texas that might work it would be better than anything in Calif due to the EPA regulations. If anyone knows of a product or anyone around Mckinney Texas who might be able to give advise it would be helpful. Thanks.

Maybe you're thinking of POR-15?

There are several products you can use. POR is not a converter but does work well. One piece of advice for POR is to get a kit with the phosphoric acid. You scrape off the loose rust, coat it with acid and keep it wet for 15 minutes, wash it with water and dry it. When you dry it, use a heat gun. It has to be bone dry. Then coat it with the POR. You can Google rust converters for other products to compare against each other.

Thank you both. The rust converter that I was referring to was a liquid that was thin like water. I think the por 15 is something more like what we may be looking for.

I used Rustoleum rattle can Rust Converter, on a gate I made out of an old rusty Patio Table, about Fours ago. Did not paint over it, and it still looks good.

So you're looking to just preserve the floor? POR-15 would probably work just fine. Be sure you address where the moisture is coming from, my guess would be the windshield gasket. Probably some more rust in that area.

Just be sure you read the POR-15 instructions carefully before you do anything - including opening the can, or even prepping the area you're going to work on.

I used it with great success on a rusty floor in my 3500HD project. I also used it on the firewall (had slight surface rust from the old insulation pad the diesel trucks got) and the frame/suspension.

The truck is in Texas now and my son's problem. The rust is worse than in the above pictures. You can see ground along the door sill. my son doesn't have the experience or money to pay to have it repaired correctly so I think he is going to bridge the area with a fine mesh wire and coat it with a few coats of Flex seal. He said the floor isfairly solid. This was the base model with rubber floor mats and yes the leak is coming from the windshield.

If it is fairly solid, I would look into doing the repair properly. It will be easier and cheaper to fix it now because it is only going to get worse. Maybe your son can buy an inexpensive welder off EBay or Craigslist or Facebook marketplace and learn some new skills. MIG welding is fairly easy to teach yourself to do with some scrap metal and practice. And since it’s a floor, it doesn’t need to be pretty, just solid. Plus he will have a new skill that no one can take away from him.

Is it possible for you to attach a photo? It will definitely take some time for him to clean the rust on this classic car.
