Rust on roof- how to treat with bracing in the way?

[ChallngeAccpted]

Hey guys, just ordered my headliner but before it goes on, I want to get rid of the rust on the underside of the roof. I was about to pull out the seats and take my wire wheel and get to work, but how am I supposed to remove the rust with the bracing in the way?! Thank you ahead of time.

Spray on rust convertor for behind bracing.. Many companies sell the product under different names. Just do a Google or Youtube search.

I used Eastwood Rust converter and Rust Encapsulator over that (several coats) I did use sandpaper to eliminate any loose rust before painting.
As Leo mentioned; There are many products out there. These worked well for me!

Eastwood Rust Encapsulator 15-Ounce (Matte Black)

Eastwood Rust Converter Aerosol - Remove Rust - Rust Converter Paint - Eastwood

Used these products on the back side of the rear floor

Some rust converter products leave a sticky residue & directions will have you rinse the product off, this will promote flash rusting; Do not do it. If working on an exterior panel use the product as directed then dilute the mixture to mostly water and wipe the residue off, before it drys. On your roof the residue will not matter, but make sure the product does not need to be removed or neutralized. For me, I like “OSPHO“. You can get it at Home Depot; you put it on full strength and leave it on to dry. Also, it can be painted over or top coated with “Boom mat” sound deadening spray or similar stuff.

SEM also makes a ready to spray etching primer, it’s excellent. Etching primer is good for light surface rust on body panels & parts, but in this case with the heavier rust I would still recommend OSPHO.

Eastwood has an aerosol rust converter product that comes with a long flexible tube that you can fish into closed spaces like frame rails or the behind the roof support areas.

This is what I used for the rust on my roof. It left a nice rust free surface to apply the Dynamat to. I picked it up at Lowes.

Thanks everyone! also PlumCrazyRTSE for reminding me about the sound deadening for the roof!

Hey everyone, little update. So I wire wheeled the roof and was able to get under the braces like I was originally asking about. Por 15’ed the roof and now going to install some sound deadening! Headliner should be in shortly!

No offense, but you didn’t neutralize the rust? You might be ok, but don’t just rely on POR 15. In the future please neutralize the rust.... I’ve been doing this a long time and I wouldn’t steer you wrong. Plus, its not very expensive or time consuming to do so.

I will take your advice when I rip-off my vinyl top that has visible corrosion bulges around the windows I will take pics and hopefully get some good advice on this project when I get to that point. Thanks Adam.
