Need help, fuel system and rust...

If you can get to the rust, get rid of it.

Don't just put some POR-15 on it and expect it to work.

It will come back, I don't care what that company says about their product. Unless it's a little surface rust, which you should sand down anyway, get rid of it. The rust, if it's rust and not surface rust, weakens the integrity of the metal, which POR-15 cannot fix. That may not be a big concern in the cowl area though.

IMO, you'll be spending more on a quart of that stuff instead if you just took your time and fix it right. Rust will spread no matter what. Just give it time.

I think POR-15 is some good stuff, but for the money, there are plenty of other options that are less of a hit to your wallet.

Now if it was a Ford......
