Window frames again :-(((

How many models I need to screw up before to get knowledge how to pain it :-(
3 days of work for nothing: priming, sanding, spraying
and finally I decided to do black frames with airbrush
(new one bought for $29 or so)
I thinned paint as recommended (1:1) and it won't stick to
the surface! It trickle down very quickly and
looks like body covered with "rain slick"
Finally I did it with hand brush and left black marks
over the yellow body

Try thinner coats with the air brush. Sounds like you're spraying too much on at once. Kind of like what I did with my RX-7. :( Or maybe your paint is too thin. I mix 1:1 in the airbrush.

Tip0: Don't trust 1:1 mixing ratio, but find your own ratio.
Tip1: Thoroughly mask everything but the windshield frame.
Tip2: Spray light mist of black for the first and second coat to prevent the run.

As for tip0, the mixing ratio depends on the brand, environment, compressor pressure, nozzle size etc., so someone else's setup most likely doesn't work for you. Always test spray on a scrap body or piece of plastic.

Also, to further ensure your mask doesn't fail, after you've put the mask on and trimmed it, spray a coat of body color or clear to seal the edges of the mask to the model, so paint can't sneak underneath the mask, no matter how thin. :)

Hiro, you can put that in your signature here (http://www.automotiveforums.com/vbulletin/member.php?s=&action=editprofile), so you don't have to type it every time.)

The art really comes in that first coat being light and the right ratio!
You want it to dry as soon as it hits the model!
After that you can go a little heavier!

I was having problems with window frames too...now I use a flat black paint marker. Looks nice if you have steady hands:) Its very even, not streaky like with brushes.

I'm still in panic how will I do it again
The paint coming from airbrush won't stick to well-dried spray can paint (it slicky as a glass surface). I'm trying to stripe down paint to the primer where I'll cover with black. But it cracks when I clearing grooves with knife.
I never tried this but that the idea: mask all frame lines before spray paint all body. When spray have dried apply "reverse mask" so frame lines will be unpainted. and then airbrush it with black
unintentially I discovered safe way to fill door lines, etc:
I paint them after priming but BEFORE apply spray paint. Spray never fill the grooves completely so black lines easily seen thru body color.

Really? That's what I was thinking of trying. The prospect of doing door lines scares me quite a bit... but it really needs to be done.

Good thing my current project is black anyway:):):)

I works great for yellow,white and other bright colors
If you want accent window frames for black body use flat black
Oldtimers benefit cause they have chrome window frames!
