How do I fix them EastCoast? Ideally I'd like this conversion to last about 2 years and then do a better afterwards... Main goal here is travel and paying back student loans.

You're right on the money! Cut the plywood as close to the tracks as you can and run a sawzall underneath. I hammered a wedge in carefully before each bolt to give some upwards pressure so they pop when cut. I've been using the Lennox heavy steel blades and have used only 2 on 68' of collective bolts so far. HIGHLY recommend those blades.

Time and persistence my man, you got this!!!
Awesome, thanks! Iíll check into those blades when I get the plywood up.

Best,

If your using POR 15 it is best to use their "metal prep" which is the same as OSPHO. OSPHO by itself is only a rust coverter. It still need to be painted over. The ideal order of operations would be to first remove as much rust as you can with a grinder, wire wheel, flap wheel, or sand blaster ect. Then use automotive paint degreaser followed by "OSPHO" or "METAL PREP" if your using POR 15. Then paint with paint of your choice or POR 15.

I've had good luck with POR 15 but have read some people have had problems with it peeling. Whatever products you use make sure to follow all the directions and you should get good results.

IDk, you'll need new metal and a few new body mounts. I'd be more concerned about those than any other rusted stuff.

Do you think it's dangerous to drive at this point??

If you're thinking that that rust shown in the photos would make it unsafe to drive, not to worry. And this is what we've been saying. There is nothing there that is cancerous. The chassis is really thick metal (compared to sheet metal on the body) and it's just too thick for the rust to make any real incursion. So, unless the bus has other mechanical issues, (which I doubt) I wouldn't worry at all.

As a point of comparison, many bridges, towers and other structural steel creations are often left in their natural steel with no paints or rust preventatives. Then the rust covers the surface and that's that. Once the structure develops a good coat of rust, the metal becomes protected and the rust itself reaches a point where it makes no more progress.

In order to have rust, you need three things - metal, air (oxygen) and moisture. Remove any one of the three and the rusting process stops cold. Thus, once the rust develops to a certain point, the metal that hasn't rusted yet becomes protected from the air and water. This is the situation with the frame rails on your bus.

I completely agree with following the directions. I've used POR 15 a lot and I love it! You can paint over the rust with the POR 15 but it will be successful ONLY if the rust that is being covered is good and tightly bound to the metal. Rust that is flaky or loose in any way will cause the peeling problem with the POR 15. Therefore, if you decide to use POR 15, simply grind the dickens out of the rust with a cup brush on an angle grinder and get all the loose stuff off.

I learned about this stuff years ago when I used to swap out my inert gas tanks at the local welding supply. Those guys would take older rusty tanks and just wire brush them really well. Then they would paint them with POR 15 and that was the end of the problems.

At the time, I was running a lawncare/landscape business in Nashville and I started wire brushing my equipment trailers the same way - with a wire cup brush on an angle grinder. Then I would paint with POR 15 and WAM! NO MORE PROBLEMS with rust. In that application though, the POR 15 would dull out pretty fast because it didn't have any UV protection. I think the POR people have changed that now by offering a type that does have UV protection and maintains a nice gloss if that's important to you. It wasn't with me and my equipment trailers.

BTW, there are plenty of YouTube videos talking about POR 15.

No- but possibly dangerous to crash.
Like I said- I'd just make sure the body mounts get taken care of. The rest is more or less cosmetic.
