newbie alert! Model Master Acryl H2O based flats Questions....

I am not EVEN going to pretend to be knowledgable on this issue: The setup here is, I am an old geezer getting back into scale modeling after an approximate 25 year absence - - really!

Here's my thing: in the way way back, when I modeled nothing but Tamiya 1:35 armor and soldiers, I was a "humbrol" and "hella" and "tamiya" paints kinda guy. Man, those paints flowed and brushstrokes just disappeared immediately! I was so hooked on those flat enamel paints, I hardly ever used my old Paasche airbrush!

Well here I am, building this dragon 1:35 Tiger II, and oh my god - after a perfect spray coat of primer, using Games Workshop "skull white" (since I wanted to base coat panzer yellow versus a darker tone  - at least, this was my reasoning for using flat skull white primer) - I attempted a brush coat of Model Masters water-based flat Acryl, specifically; panzer dunkelgelb 1943.

Let me say this: whiskey tango foxtrot!?!

Now that I've basically consigned the hull deck and engine cover to a butt-ugly initial coat of yellow, am I going to have any luck with a second coat helping the brush strokes disappear?

I am already going to move on and forget these H2o-based paints with this experience, and I'd really like to get the best recommendations for the old-school flat enamels of yesteryear that I remember.

Can those old flat humbrol tins be found here in northern VA, or by internet?

Thanks, veteran modelers!
