Starting Mobile Vet Unit 1 of 3

Hello!
This is my first post for my saga of my skoolie to mobile vet clinic conversion project.
Of some of you know, I just purchased three buses from two different school auctions. One is a 1996 International Wayne, and the other two are 1981 International Wayne. The latter two already have the seats out, as they were used for band equipment buses. I am starting with one of those. The insides are lined with nasty black outdoor carpet. I conned two child slaves into helping me pull out carpet today. I was fairly dismayed to find rust in some areas of the back that had eaten holes through the floor. I was planning on prepping and painting with Rustoleum rusty metal primer, and then laying a subfloor. Should I paint underneath the bus too? What about reinforcing metal under the bus due to the holes?

I would treat the floor and then fasten some sheet metal over the bad spots and then keep going like there wasn't any rust. Put a couple coats of Ospho on it then some primer and paint. Primer and paint the new metal too. It will last as long as the rest of the bus.

I have never used ospho before. Researching it, I am afraid it's going to eat large holes through the floor. How do you know how long is enough for this stuff? Is there a gauge of sheet metal that I should place over the bad spots? Should I have any concern for need for reinforcement on the underside with the holes being so close to the outside walls of the bus?

The name of the mobile veterinary service is Healthy Pets USA and our colors are red white and blue. We are painting the buses ourselves and wanted something eye-catching.
I came across this bus from Thomas and plan on copying, with the exception that I may do something different for the stars. Either no stars and just red white and blue, or use a contact paper star cut out as a stencile for the stars.

I used a bug sprayer to apply it. You can brush/roll it on if you want. It will not eat holes in the metal. It stops further rusting. Just put it on and when it dries it turns white. You may need a second coat. It kinda turns to powder when it dries. Use goggles/respirator. When it is dry sweep the powder up, prime/paint over the Ospho and lay some sheet metal over where the bad spots are. The easiest way to fasten the new sheets would be to use pop rivets. Do you know how to use them? You could tack weld them but I assume you are not a welder LOL. You won't need too many, just enough to keep it in place. You could reuse the ceiling panels if you are removing them. You can use any thickness of metal. I would not go super thin though. Go to a metal supplier and look at the different gauges. I would think 20 or 22 gauge would be good enough. Just make sure to clean the new metal good and apply primer/paint to protect it. It should outlast the rest of the bus. I would not worry about reinforcing it underneath the bus. Just overlap the edges of the bad spots a little bit. Please don't hesitate to ask questions. I know you will have tons of them. Good luck.

Do you have power where the buses are at? Assuming they are in Cypress and haven't floated away I can swing by on the way to work and tack sheet metal in for you, my welds ain't pretty but they (usually) hold

Most buses use 15/16 guage sheetmetal and even covering or repairing I would go with nothing less than original rotten metal? I like to use stainless steel rivets for metal to metal connections because the stainless is stronger than what you are attaching and can resist all the twisting and turning of the metal as it is going down the road.
When you look for sheetmetal if you want to paint it.
There is raw/non-galvanized that will soak up several coats that you have to ask for in the 18-26 guage sometimes the thicker 16-12 guage is available but not common in a workable dimension for the homeowner.
If you do end up with galvanized sheetmetal to paint (which i would use)you can see a coating/clear sheen on the metal that needs to be taken off before it will ever hold paint.
More time and money
Use vinegar to take the coating/sheen off and buy a self etching primer.
Going to the big box store they are going to sell you a cold galvanizing compound in a spray but the metal is already galvanized?
If you choose this option find a commercial paint supplier and they probably have/can make samples in quarts which will cover quite a bit as far as patches go.

Fiberglass and paint

Hello!
I am going to be working on the outside of the bus with paint while I'm working with the inside of the bus for metal floor repair. The nose of the bus has some damage, and I have never done fiberglass repair before. I would like to repair all three buses for fiberglass at the same time so that I can mix one container of the resin. I know that I want to repair the outside of the nose with the thinner fiber sheets and resin. On the inside of the hood, I can see that the fiberglass has been patched with heavier fabric where the mirrors go through the hood. Im wondering whether I should make additional patching or just leave it until it becomes a problem. Ill post a pic shortly. Do you prime fiberglass after you apply a patch when painting?

In regards to the floor, thanks for all the advice on the sheet metal repair. Im looking for a supplier in Houston. Im sure there is no shortage in this industrial city, just gotta find one close. I have not done riveting before, but I think I can do the pop rivets no problem. I may take you guys up on your offers to come help soon once a get the materials.

HealthyPetsBus: I have had a really outstanding (and decade-long) relationship with Steel Supply, Inc on Telephone Rd just (barely) north of Loop 8 in Pearland. IMHO, these guys are just the bees knees when it comes to stocking what I need. Tube, sheet, angle, rod... You name it and they got it.

Website: https://www.steelsupplylp.com

Disclaimer: I have NO financial interest in the above vendor whatsoever. But they have LOTS of neat stuff, will cut anything to size, can deliver withing 50 miles, and have always been a patient, good-hearted resource for my many metal goofings. YMMV.
