I just acquired the Sierra powders and think they give great results. I start with a light coating and just add more until it looks right. The only negative I’ve notice is with the gray powder, I’ll occasionally get a black streak. I’m guessing it is because the powder formed a small clump that didn’t get dyed all the way through and when I brushed it on, I crushed the clump which left a black streak instead of a gray one. It’s not a big deal if I take care of it immediately. I just wet a fingertip and rub it out, then reapply the powder.
I dullcoat over my powders. The only thing to remember when doing that is the amount of powder you put on the model will decrease when you spray the dullcoat.
I have found that if you do not use something…you can leave fingerprints on things…I had a couple of pieces of rolling stock with big thumb prints on them…and yes…the dullcote will fade it a little…but still a very easy product to use and make things look truly weathered…my best adviCe is do what i do…try everything until you find what works for YOU and ONLY YOU…
Greg, check out the Bragdons if you can get your hands on them. This was recently discussed in a thread but the Bragdons has adhesive mixed into the powder. I was very intimidated the first time I weathered a structure but it turned out to be easier than I thought. I am very pleased with the results. Also, I don’t want to sound lazy by adding this, but I don’t seal anything that I weather with Bragdons. I haven’t had any problems with the structures either after almost 3 years in place for some of them.
I found that makeup brushes and sponge wands work GREAT for weathering with chalks. I found a pack of chalk sticks at Wal-Mart. I use the blade of a hobby knife to scrape the chalk into a pile of powder.
It can be done either wasy. Most using Dulcoat, however , are using the small spray can.
I actually prefer to airbrush Floequil flat finish. In a pinch, I’ll shoot a model w/ testor’s spray. It usually goes on in a fairly decent layer but nothing compared to airbrushing especially the Floequil flat. Once Testor’s is dry the flat finish will hide any imperfction in a sometimes heavy or rough coat. I may just be too picky as many have no problem using Testor’s can all the time. Your choice.
