Hull fairing questions

Okay guys, thank you very much for clarification. I imagined that primer is much closer to filler than it is to paint. So if I were to use a proper primer, and noticed some surface defects that needed to be filled, I understand that I would be using filler epoxy there, not more primer, correct? If so, then I suppose there is no other kind of primer that could happily sit between different coats of filler epoxy without delaminating afterwards?

yup...epoxy primer...epoxy filler
Well, crap. I guess there is no way around this. Guess I'm stuck. One of my epoxy suppliers wrote me back just now (I sent inquiries about epoxy primer to 5 suppliers that I have here in Lithuania). This was the only one that wrote they have epoxy primer available. Price is $364 a gallon. Yeah, that is not a typo. Compare that to regular epoxy that is ~$50 a gallon around here...
Okay, I will keep searching. I have taken enough of your time already. Thank you very much for all the information, I really appreciate it.
That isn't an unusual price.
I've seen it retail for $85/ quart in California
All depends on your final finish appearance expectations. Do you want the perfect 10 found on multi-million dollar mega-yachts? Or a 1 done by a toddler using finger painting?
Home brew epoxy fairing compound can be 250 mils thick with 10 mill deep defects common
Quality high build primers can be applied to 50-150 mills Dry Film Thickness. They usually sand to less than 1 mill deep imperfections.
High end marine or automotive paints are 2-4 mills dft.
Quality oil based paints 5-10 mills dft
If a level 8.5 finish is acceptable,
Then half a dozen coats of oil paint will suffice.
If that elusive 10 is the target,
Then expensive primers orA hundred coats of two-part paint with be required.
The toddler doesn't care if it's cheep or expensive paint
As long as it is a pretty color
Your not waisting any of my time

Probably yes
For intermittent submersion. If it is a true oil. Or thins and cleans up with solvents
Some acrilic is oil "fortified". It is crap on a stick. Don't use it under water at all! It thins and is claimed to clean up with soap and water but doesn't. Solvents won't clean it out of a brush either.
