I want to weather some wooden models with either Bragdon or Doc O'Brian weathering systems. Is it necessary to first spray wooden models with Dullcoat or will the powders adhere when directly applied to the stained but unsprayed surface?
Does spraying a wooden model with Dullcoat seal and protect the wood from warping due to moisture besides fixing the weathered powders?
This is a fantastic and extremely helpful thread and I have found a lot of useful information on it. I wish there was an additional forum for weathering techniques.

So true. Layers...layers....layers.....

I also use goache, hairspray, diluted acrylics, alchohal (bad spelling) and of course, the common denominator, water. Dont forget about the effects you can get putting alchohal () on dull cote. it turns white, and with a little practice it is a great technique. Plus, if you screw up, spray the dullcote again and its gone!One of my favorite techniques is to mix burnt umber, raw umber and burnt sienna goache and dab a cosmetic sponge on it. Then dab the sponge on paper until its just leaving little speckles. Do this on the model and it looks like paint flaking and rusting.
I find that the factory paint finish on all my newer Atlas and P2Ks ,although don't seem to glossy, just don't want to hold the Braegdon powders. I hate to dullcoat the entire engine only to do some slight weathering. Any suggestions? Have really worked the powder in hard a couple of applications and it will just rub of will light handling. It is OK for weathering the cracks and crevases.

I discovered the answer to my own question. Weathering powders and chalks adhere extremely well to wooden surfaces - no dullcote or other fixatives necessary.
