Bus Demolition Day 19: Rust Prevention

Our floor beams were clean and shiny so we were ready to paint them with Rustoleum - a rust preventive coating.  For the really bad areas that have a lot of pitting we applied POR15.

POR15 recommend you wear gloves and respirators and follow this 3 Step Process:

  1. Use a rag to clean the metal with the POR15 Cleaner and Degreaser 

  2. Apply the POR15 Metal Prep mixture with a rag. This actually scuffs up the metal, to help the sealant grip to the metal

  3. 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.

Rustoleum Primer Paint

We used this Rustoleum primer to coat our metal floor beams. It is a durable protective coating with excellent rust prevention to be used on metal only.  It provides a base for excellent adhesion and withstands demanding, heavy-use environments.  

POR15 Rust Stop Kit

Por15 provides permanent rust protection, but is best for small areas.  We used this on the areas that contained the worst rust, while painted the rest of the bus with rustoleum. 

3M Respirator

This 3M Respirator provides 95% filter efficiency against solid and liquid aerosols as well as certain organic vapors, a must when applying the POR15 and Rustoleum application.
