If the op was to use a self priming paint like zinnser perma white they would be ok for a small touch up.
Oil based is ok if you go for Matt or eggshell but as a gloss it's a waste of time it just yellows far to quick. A mate of mine done his whole house in oil, 8 months later it's yellow except for areas around the windows..
Oil based might be good for business as no sooner do you finish you got to paint it again.
It's also an arse to clean the brushes, nor environmentally appropriate
You may well be correct about oil based gloss. I have not had a customer ask me to use interior OB gloss since 2010.
Frankly, I find the suggestion that I recommend oil based paints because I don't care about the longevity of my work to be highly offensive. I do not know what you do for a living, but after 30 years as a professional decorator I find that oil based paints lay off more evenly and are far more durable than waterbased paints.
I spend thousands on Festool dust extractors and sanders. My work environment is clean enough to enable me to put my oil based brushes in a Brushmate and use them on the next job without the need to clean them for (literally) years.
It is undeniable that waterbased paints are better with regards to the volatile organic compounds released whilst they cure. They do however require much more electricity to manufacture and contrary to popular belief many do release toxins. I am often presented with woodwork that has been "toshed" with waterbased paints when houses are put on the market. They are a nightmare to sand flat because the waterbased paint clogs my abrasives. The labour (read:energy and cost) to sand them is far greater than sanding oil based paints flat.
I personally use oil based paints because I want to provide a high quality of finish and want the job to last as long as possible. Given my exposure to the solvents released, yes, I would rather use waterbased paints but at the moment I am not willing to compromise the quality of my work.
