Patina Preservation: Am I on the right track? - Raleigh Tourist DL-1
 
What is the best way to remove surface rust? After rust is removed/halted, what is the best way to preserve/coat the affected areas? Are there any other steps I should include in the plan below? Suggestions welcomed.

I have a '75 Raleigh Tourist DL-1 I enjoy cruising around nearby Lake Como or when I feel like a leisurely cruise:

It's in pretty good shape over all, but the fenders have a bunch of rust:

To treat the rust on the fenders (I'll be leaving the frame alone as the paint is in pretty good condition), I am planning to use a brass wire wheel on a Dremel. I've also read that people use a single edge razor blade to scrape off larger rust spots, so I might give that a try as well if the wire wheel can't handle some spots.

Once the bubbly, powdery rust is removed, I'm planning to scrub (formerly) rusty areas with Barkeepers Friend - avoiding paint when possible since I understand it is a mild abrasive. I'm hoping the Oxalic Acid in Barkeepers will also take care of some of the rust. Would using Ospho at the point be redundant or have some unintended consequences?

Finally, after rinsing and drying, I plan to use tips I kindly got from Prowler to coat the fenders in boiled linseed oil (BLO). A treatment of BLO seems to be a pretty C&V appropriate way to add a little sheen to the less shiny fenders and to give them a little protection for all the fine work they've done to keep the frame protected.

Any suggestions to improve my plan would be appreciated.

You might just want to knock down the loose rust, sorta smooth it out then treat with rust converter. It generally dries black anyway. These are mudguards, they show patina proudly!

3speedslow What would you suggest for a rust converter? I would prefer something with low toxicity.

Edit: Would a scrub with Barkeepers Friend count as a rust converter, or is that more of a rust remover?

I would brush off the crusty stuff, wash them well, and use Evaporust in a wallpaper tray. Wash again after treatment, dry, and do a paint touch-up. Black is easy to match.

Rustoleum has a good product. Barkeeper is not a converter but a remover. Treating it as has been said will work but is never a final call, Rust never....

Afternoon's work
 
I took some time this afternoon to remove surface rust with a brass wire wheel.
Before:

After:

https://cimg6.ibsrv.net/gimg/bikefor...8038c4332b.jpg
I like the results so far, & if a rust converter will turn the rusted areas even blacker all the better.

Next step is a rust converter. @3speedslow suggested Rustex by Rustoleum. Has anyone compared it to Ospho or know what the differences would be between the two?

Thanks all for the help & suggestions.
