Use a rag to clean the metal with the POR15 Cleaner and Degreaser
Apply the POR15 Metal Prep mixture with a rag. This actually scuffs up the metal, to help the sealant grip to the metal
Apply the POR15 Rust Preventive Coating with a paintbrush
We have also seen other people use a steel brush to grind the area to help the sealant stick to the metal, so we tried this on one of the bad areas too to see what worked best. Don also tested on a small area what would happen if he didn’t do step one and two and just applied the coating to see if all that prep was really necessary. It all worked great, as far as we can tell it worked just as well whether you prepped the metal first or not.
We bought a POR15 kit to test it first and see how it worked. The kit only has a 4oz Can of the Preventive Coating (plus the cleaner and metal prep bottles) but you can buy larger cans (of the coating) up to a Gallon.
Be very careful with this stuff, it does not come off your skin. Don, unfortunately, found this out the hard way. It’s okay though, he just has to wait for about 6 weeks for the skin to naturally take it off.
The rest of the metal frame we painted with Rustoleum Spray Paint. Make sure you use all your protective gear here too: gloves, respirator and eye goggles. We tore up some old boxes and used them to cover parts we didn’t want to spray like hoses and the holes going down into the luggage bays.
Super hard work but we now know that we have done everything we can to prevent further rust from developing and will have a healthy, clean and strong tiny home to live in.
