If you want an even coat from dipping, I think you'll find several coats
of thinned paint will give a more even coat than one coat of unthinned.
I use a similar method for painting the inside of steel masts. I weld a
cap on one end, half fill with thinned Rustoleum, temporary cap the
other end. Then roll the mast while tipping it, uncap, pour out the
paint, and let set with open end much lower than capped end. (both ends
can be temporarily capped and then left open during use.
I just don't like open pipes as the wasps tend to use them for homes.
They even managed to get in the exhaust for my shop heater last summer,
So I fire it up a couple times a week at night to keep them cleaned out.
As for rust proofing, I weld caps on both ends, drill and tap the center
of the cap on one end, put about a quarter of a can of LPS2 sprayed in,
epoxy in a set screw flush, roll and tip as with the paint. No welding
after the LPS application. There may be enough air mixed with the
solvent to blow an end cap off which is quite dangerous which is why I
use the setscrew.

I'd rather poke my eyes out than use a roller... I invested in a NICE
HVLP gun (body shop quality) a long time ago and built an air dryer
system to hook to the compressor for all the tools and an extra module
that additionally dries the paint gun air supply.
And I have a tote with all the paint tarps to rig up a small paint
booth. Use some A/C fans I scrounged for exhaust venting...
IF I couldn't use a spray gun, I'd rather use disposable cotton gloves
over surgical gloves and put the paint on LITERALLY by hand... We used
to do this in the oilfield... WAYYYYYYYYYYYY faster than a roller.

HVLP spraying is fairly efficient, but there is a learning curve and
the initial portion of the curve can be high waste. Depending on the
equipment, cleanup can be a royal PITA. Inexpensive equipment may
have plastic parts that are vulnerable to paint thinners as benign as
Mineral Spirits) even though most paint requires little thinner when
used in HVLP guns.
Personally I don't like the results with rollers on tubes and much
prefer the HVLP, EXCEPT being inherently lazy, I really dislike the
cleanup.
