yellow paint problem

First, welcome to the forum !

Whenever I paint yellow, I always put down a base coat of flat white. Yellow is Very difficult to paint over plastic. Build it up slowly, coat after coat. It takes a while, but it will cover. The yellow fuselage band in my signature pic is painted over a base coat of white.

Hope this helps !

Welcome to the Forum!

Pix is right on. He is the resident Luftwaffe Jedi Master, and he has posted many fine Bf 109's on this site.

I totally agree with Pix about laying down a white base coat.
I prefer Floquil's Reefer (flat) White, which sprays very well right from the bottle.

For the yellow, I use Aircraft Colors RLM 04 (the old Aeromaster formula). You can get it from either www.squadron.com , or www.greatmodels.com .
This paint is excellent, and again can be sprayed straight from the bottle (assuming you have a fairly good quality airbrush).
As Pix said, you must be patient, and lay it down in very fine coats. Don't get in a hurry (as I have done) to get a depth of color too soon. It may take three or four light coats to achieve the look you want.

Here's a pic of my Dornier using the above described paints:


All the yellow on this model was done as described above.

Hope this helps.

Yeah, EVERYBODY has the coverage problem with yellow. Just a fact of life. As the others mentioned, start with a light colored base and it will cover a lot better.

As to your spraying problem, I haven't seen any difference between yellow and other colors in that respect, although I did have that problem with some ModelFlex acrylic. It sounds like it may be drying super fast, right at the nozzle. Try thinning it pretty well, and spraying with a low pressure as close as you can get to the surface without causing problems. I use Badger airbrushes and spray at about 15 psi from a distance of 3"-4".

Oh yeah, welcome to the forum! Hope you enjoy it here as much as the rest of us do.

Yellow sucks!

I don't know why it would spit out. You should have it airbrush just fine, but with very poor coverage. Once you solve your spitting problem then go back to painting your model, but prime your model with white first.
