More rust

[championbaum]

What do you guys think I should do here, it’s in a tough spot to reach, under the passenger seat where the seat mount is welded on. I can either cut it out and reweld to get a wire wheel in there or treat it as best I can with naval jelly and then maybe a rust reformer.

Any other options I’m overlooking?

Phosphoric acid products. Naval jelly is kind of old and expensive chemistry. Itw not "bad"....it has some phosphoric acid...but also has sulfuric acid and a bunch of polymer stuff......and its roughly 50 cents an ounce. You can buy a gallon of phosphoric acid product that (some of which like Jasco mix out to 2.5 to 3.0 gallons) is easier to use....and rinse away and neutralize.....for around 10 cents an ounce. Or you can get Kleen strips version of this at Home depot for about $15 a gallon. Ray

I have found that super coarse sand paper and manually rubbing down by hand can be quite effective in hard to read places, for example the air box on the nose. Sure it is slower than a wire drill bit but it can deliver decent results....

What you need to do is grow yourself some proper rust
I have plenty I can ship over the pond to you

I wouldn't go cutting out steel to to gain access to that area. just clean up best you can, then treat and paint as mentioned.

Ok so it seems the bus has grown some real rust as zerothehero requested, in another tough to reach spot. I believe I can cut it out from under and reweld a patch, but I’m not so sure on the driver side (both sides have rust, passenger side is worse), at least with the nose intact, I may try to clean it up on the driver side best I can, treat multiple times inside and out and patch it with fiberglass and POR-15, but the driver side issue is smaller than the passenger side. It seems water has gotten in, and saturated the foam that is in that basin in the nose and the metal really suffered.

So again this is in the front of the bus in the basin of the nose, I can’t get a wire wheel in there at all, so I guest best option is sand paper and time right? Any other recommendations would be appreciated.

That's more like it

Is the hole in the deformation panel?
Your best bet is to cut and weld from underneath as you suggested.

If it's the deformation panel you can replace the whole panel, which could be beneficial if it's all gone a bit crusty.

Having said that there's nothing wrong with a decent patch job to see you through the camping months.
