i'm using Tamiya Liquid Surface Primer with a Iwata 0.2mm airbrush. I'm spraying at about 10-12 psi at a distance of about 3 - 4 inches (~7 - 10 cm). Usually 3 coats sanding a little bit before the last one (grit 2000). Do you think is ok ?

I agree with the folks above about using a different color primer. Tamiya grey would be a great choice, you chose a first-class primer. Yes

I'm not sure about shooting it though a .2mm needle/nozzle though.

I agree with OMG. The gray is a little rougher, but it's easy to polish it a little.

 

I’d second that. White paint over white primer on white plastic would be too much of the same thing. A dissimilar color primer such as gray would give far better results.

 Modeling is an excuse to buy books.

There comes a time where you can just spray it on because you are that accustomed to it. I'm answering here mostly to bump your message though, others can probably speak more authoritively about the product you want to use.... Anyway, meanwhile if you're priming white plastic and your goal is white primer with white paint on top of that, you could always shoot a coat of light grey primer first. Then just recoat with white primer when you're happy with your surface. I did that with yellow plastic recently, not to see my work but yellow plastic has a yellow glow through white primer in the right light. So I shot grey as a block, inside and out incidentally.

Maybe more answers are headed your way !

Dear all,

I would like to ask you how you manage to prime a white surface with a white primer, how can you check that the primer is spraying fine and smooth if you can't see the cromatic difference with the substrate plastic ? Only by feelings ?

Actually i'm using Tamiya Liquid Surface Primer with a Iwata 0.2mm airbrush. I'm spraying at about 10-12 psi at a distance of about 3 - 4 inches (~7 - 10 cm). Usually 3 coats sanding a little bit before the last one (grit 2000). Do you think is ok ? Results seems to be quite ok... 

Second question... can you explain me which are your parameter to say that a surface is properly primed ?  

Thank you in advance!
