Hi Starwars dude. Please take my following comments as meant to be helpful.
"Anonymous" may well be Manstein's Revenge, who was permanently banned in 2012. Or someone else long gone.
Mike V is Mike Van Buskirk. He is a master at the airbrush, but has not been active for a long time, at least a decade.
And you'll notice that the post you replied to is dated 2004, which is fine except that you've posed a question that you won't get an answer to from either of those guys.
I have no idea what "dob" means, maybe daub. If so, I think that's bad advice.
OK, nuff on that. Here's my own two bits.
As was said, don't create brush marks to begin with. Removing them NEVER goes well for me.
In addition to a decent flat brush, when hand painting it is important to thin the paint down quite a bit, and plan on multiple thin translucent coats.
I think we all started as kids trying to create a thick lake of paint that would somehowm "self level" and dry with a still pond surface effect. Even if successful, any detail would join the lost city of Atlantis. Of course we didn't care.
I like brush painting in particular for small part detail.
