And as a follow up question on the linseed oil: have often wondered about how
the aircraft guys welded up that tubing that had been treated with the linseed
oil on the inside. What does the welding do to metal that has been treated?

Aircraft guys have been doing that for years. But I have never tried to prep
metal for paint that had been treated with linseed oil. How would you ever get
it cleaned out/off enough to hold paint if you get it on surfaces that you want
to paint later?

Linseed oil soaks into the pores of the metal you treat it with. Good for
enclosed areas that you can use a fill/drain process on but not spray into
easily. Don't use it on areas you may want to paint later because you'll
spend days with acetone getting it back off.
Use boiled linseed oil. Plain linseed oil will take MONTHS to dry. Boiled will
dry in a few days but while it's drying it is penetrating and sealing.
Plug all the holes in the rocker except one, fill at least halfway with boiled
linseed oil, rotate slowly for a while, then drain and set it down in the same
position it will be welded into the bus (so the "down" side that will
collect water later will collect excess linseed runoff while drying).
The guys in this forum are discussing using it as a coating while waiting for
paint (not ideal) but this one comment is notable.

"Re: Linseed oil as rust preventative?
I scrapped an Aeronica Chief several years ago that was at least 50 years old.
It had flipped over in the wind and I wanted the engine. Airframe was bent up
beyond practical repair. I donated the tubing to a local A&P school for
practice welding. I cut it up before giving it to them and was amazed at how
well all the 4130 was preserved that had been treated with linseed oil. A lot of
the untreated but painted surfaces had some serious rust issues. "
