Slowing down rust

[vince72]

Hey Guys,
What is the best way to slow down the rust on my trucks roof? I am not ready to paint it but I’d like to slow the rust as much as possible

It’s already put a hole through the roof skin. No stopping that without cutting out the old and repairing it properly. Do you have water getting in the cab?

The hole is not all the way thru & no water in the headliner yet. Id like to slow it much as possible

You can try a rust inhibitor. I wonder how the channel looks underneath. The thing is with any rust inhibitor is that it probably won’t be able to penetrate to everything that’s bad under there. I’m assuming there is more than what we can just see.

Im sure there is more. I just noticed the rust last week.

Are you planning on having the roof re-skinned or patched?

If it is not horrible patched, but I have not seen how bad it truly is

The hole might not be, but the rust probably is. Bite the bullet and get that cut and patched ASAP. Rust is a cancer.

Looks like it's all the way through and the structure underneath is also rusting. Putting stuff on the outside to slow the rust isn't going to stop it. It's bad enough to continue rusting from the inside out. It needs cut open, cleaned up, some paint/epoxy, then patched.

My DD Honda Fit had bad paint in a few spots when i bought it in 2012, like it was splashed with acid or sone chemical. Eventually, the hood spot rusted through. I wire wheeled the hole edges, hit it with sone rust converter I had. Then filled it completely in with black JB Weld. Did it stop the water going in hood, yes. Does it look good? No. At 195k miles, you earn the right to look anyway you want imho.
