Polyurethane does not last forever, even the good schit that you can't buy in a spray can. Even on repainted cars, the life of the clear coat is less than half that of the factory clear. Once it goes to hell you have a big mess to deal with so you're screwed. It might take 15 minutes to do a recoat of BLO after it lost it's sealing capability in 5 years or so. BLO is the way to go on something the OP has.

You know what. Not even going to argue with you on the subject. BLO lasts 5 years huh. Good to know

@J-Shooter unless you know for a fact that you will be keeping that bike forever and ever, it might be unwise to put something that can't be reversed on that bike. Your effort may not be appreciated by the next owner. Boiled linseed oil gets my vote.

I remember one Caber argued that rust isnt patina. So if you want to preserve the patina then according to him you can remove the rust.

1week after the rust job on a Micargi frame. 1 non running coat of a matte polyurethane

At least 3+ years sitting untouched in the SC weather. Pics taken tonight

I don't see a drastic difference other than phone flash due to the dark. You judge & decide for yourselves.
Bike still feels like the same way it did when bottle rusted & can sprayed.

Will post daylight pics as promised if need be.
