LOL, I have one of those and never knew what the hell it was. Came with my toolset. Guess I'll try and use it

Thanks

Rust? it hasn't in it's 20 year life yet, why would it start now? It's a sticky tar just to hold the insulation in place.

I plan to use a 50c extra wide plastic spackle knife to do a quick scrape and whatever comes off comes off, and whatever doesn't gets insulation over it anyway. I agree if it hasn't been an issue yet, I doubt it will be to leave the gunk on there.

(That doesn't include the 2 panels I have that have visible rust, which will be treated appropriately first instead.)

It was hiding this-


After lots of work we ended up getting it all cleaned up and primed.

It traps moisture and over time that causes corrosion man.

Come on Charlie, you show one pic that you have no idea what caused the rust. Almost ALL of us have that stuff on the ceiling and no one has any rust there.

What are you asserting, man???? I'm glad I didn't leave that garbage. Laziness is not the road to success.
The rust was from multiple sources of moisture. Condensation chief among them.

But you blamed it on the sticky stuff and I don't think you can verify that. The stuff has been on my bus for 20 years, there is no rust there at all.

I removed 40 feet of bus worth of it. I can verify that it traps condensation causing rust. No one's holding a gun to your head forcing you to remove it but don't go calling me a liar cause your bus is different.

Good idea, I want one of those! I wondered if it would work for the glue on my floor. I scraped it all up with about 40 razor blades instead. Regardless, one of 'em is on my wish list. I'll walk out of Home Depot $130 poorer one of these days.

This actually works pretty good. Its like cutting hair at a barber shop. Gonna order a an accessory kit with different attachments

Still wish i could use a pressure washer to give my bus a good cleaning though

Thanks for the tip!

Harbor Freight has them for $20 to $40. I've not used one so I can not attest to their quality.

Dang!! Our bus definitely has some insulation left stuck to the ceiling that I'm about to go scrape off. Now I'm wondering if it would be worth priming/painting even if we don't have any rust, just to protect it in the future.

You did a really great job on it! Did you spray foam by any chance? I'm wondering how spray foam would interact if I decided to go the extra mile and paint the ceiling.
(This skoolie is my permanent full time home so I am trying to do everything preventative possible)

We sold it. The guy went with foam board.

I found the same thing on mine by complete accident.. I was using a shop vac with an attachment when I was sitting on the floor and in my attempt to get the hose untangled it stuck to the ceiling and removed a chunk of that insulation adhesive! Unfortunately, there was rust underneath I used the shop vac on the rest of the ceiling and in almost every section there was rust
If you wouldn't mind how did you treat it? Should I treat it like the floor and remove the rust and adhesive then ospho it and paint with Rust-Oleum rusty metal primer?

Yeah. I'd get the black goo off and treat it. I used ospho. Some areas I used Rust Reformer. The gallon, not the spray can.

Try scraping off the black stuff. If that doesn't work try a wire wheel on a drill. If that doesn't work do what I did and get aggressive with aircraft stripper. But be damn careful with that stuff. Its no joke. Read the directions and warnings. Its very corrosive. Don't get it in your eyes or skin.

Thanks, I appreciate the help! I suppose I should be grateful to my wandering shop vac for unearthing this issue, because otherwise it looked just fine!
