Hola!

Now this is something completely new for me, so I need all advice I can get! Im doing a SdKfz 250/9 from DML and I'm painting it in a 3 tone hard edge late war camo pattern. Ive already sprayed the half track in its base color and now Im going to paint the camo. So my questions are:

What should I use as masking device? I need something that I can use to make a somewhat wavy pattern.

How should I spray it once the masking is on the model? Like high/low preasure?, more diluted paint then normally, thicker paint etc?Also what angle is the best to avoid "leakage" under the mask.

Now, keep in mind that I am a newbie airbrusher too. Just finished airbrushing this half track and this was first time to airbrush in over 4 years. Im impressed how nice and easy it is though to air brush! Hope you guys can help me with this!

Okay, if you HAVE to mask...You can take your pattern and enlarge it to 1/35 scale, cut out the mask and apply it to the model with folded over tape as close to the edge as possible. If the tape is low tack, transfer or copy the patter to the tape and cut it along the lines and apply.
I don't mask camo, but do occasionally have to mask details. I don't make any changes to pressure or viscosity. To reduce seepage, angle your airbrush away from the edge and keep the airflow low. Your initial lines should be pretty thin. Go back after and fill in the spaces as needed, remembering to "keep indide the lines" For this part, your AB should be back to 90 degrees to the surface and you can increase the airflow.
Let the first color dry and repeat with the second color. :-)

I've done a bunch of hard edge multi color camo.
I first draw out the camo 'blobs' on paper first.
I use 3" wide masking tape. I take about a 5" length and stick it down to a piece of glass or mirror or ceramic tile. I transfer my pattern to the masking tape and use a #11 to cut it out. I then check the stickyness of the tape and if it is too sticky still I first push it against my pants. This take a bunch of the stick out. I then fill in gaps with generic shaped pieces of tape.
As far as pressure I spary at about 15 psi. I don't thin my paint much, probably a little less than normal. This helps avoid drips. Spary light and slow.
I would progress through the color scheme from light to dark so the dark color covers any light colors. The paper templates help 'mate' two side by side blobs. Use one as a guide to make both curves identifcal. Just overlay one on the other and trace the 'mated' arch.

I hope this helps. If you have more questions please ask I'll explain in more detail if needed.

Thanks guys, I've got some low tack masking tape from Wal-Mart used for stencils that I'll try to work with. I'll be sure to let you know how it all goes
