Holes in Floor?

Hey bus world! Been scanning the forums for advice on our tiny home project. We are at the empty shell phase. 1989 Thomas, Cat engine. We aren't doing the ceiling and walls because of time restraints. We are gonna ospho and rustoleum the floor. But We are having a hard time knowing what to do with the seat holes in the floor. I've read some quick advice about aluminum tape and car windshield sealant, but not how it was applied. I've dug thru a few conversion thread, but we are held up at this point so just asking for HELP seems like the best plan. We really don't wanna mess this part up and rot out our floor. Trying to live and travel in it for 5-10 years. We have a product Sikaflex 221 that is a non latex caulk for metal that has more flexibility (for going down the road). We got it for our windows, hoping it might work for th floor. Any advice is welcome, please tell us what's worked for you.

My process was angle grinder for cleaning/scarring surface. Wiped with acetone to further clean. Applied a 2 part epoxy around the hole, then caped it with little 1"x 1" metal cutout. On the smaller holes I just used epoxy.

Plan on covering/Insulating the floor down the road. So the little metal cutouts wont even be noticed.

FYI I am a complete skoolie noob as youself. So take as much or as little weight in my technique as you want.

Have you driven your bus with these attachments? Worried that Bondo will crack with too much movement.

OK I'll get flamed by the usual suspects for asking this, but why can't you put the original bolts back in the holes with some locktite and grind them flush?

Took it on a short road trip last weekend. city/highway/gravel roads. Everything seems to have held. Time will tell though. Like I said, just getting started on this project myself.

Seems like a practically good idea but we don't have the bolts. We were lucky enough to buy it already empty.

i was at your point a month ago. I had bought a welder for various repairs ($299) it is a wirefeed flux cored welder so very simple to use. Do not be afraid to weld, it is not as hard as you may think it is. So with that being said i welded ALL of the floor holes in my bus and was easier than putting glue or tape down. Honestly might have been 10 seconds a hole, if that. I turned my welder to the lowest amps for thin metal, put it on the edge of the hole and dragged the pool around until it filled the hole, it was molten hot so it expanded right ibto the hole. Did 200+ holes in 2-3 hours. Also ospho is a touch expensive compared to what i used. Brand was kleen strip phosphoric cleaner that converted rust and prepped metal for paint it was $15 for a gallon at home depot, couldve did 3 buses with it, also bought a hand pump aprayer people use for fertilizing and stuff for $9 and you honestljy cant get much better. My build is the 1992 thomas international, just got done doing it so check it out. I also typed this on my cell phone so sorry for the typos as i was too lazy to correct them.

Did you do rustoleum over this? Would you recommend it?

Yep i did used professional rustoleum was oil-based and we choose gloss black but there was anything from green, white, red, black and more at hone depot was $26 a gallon so we got two and it did the whole floor, back, and side panels with about 1/4 left in the second gallon when all done. The paint and phosphoric cleaner were in the same section just the next aisle it was all pretty easy to find.

Like BurlKing I welded all the upteen jillion holes in my floor. That way I know the fix is permanent and not going to let go or fall out like tape or Bondo.
And definitely yes on a good quality rust inhibitor or converter.
