His book?
..... to see your various mixing formulas, and the cars/finishes they work best with. ANy chance of getting you to do a summary post with some sort of table?I'd buy you a beverage at Franklin's in payment, but you'd have a LONG stumble home these days.
P.S. Since I've lived in both Boston and Vancouver now, I can't lose, but I think this is Vancouver's year. If they win, the beer is on me.
Here's an executive summary:* Spray application. I make a batch in a 1 oz Floquil-type jar as follows: fill the jar ~20-30% with Microscale Flat or other water-based flat finish, add about 10% Polly Scale Dust, then add a dollop of Zinc White (a "dollop" is about an 1/8 of a teaspoon) and about the same amount of Transparent Oxide Yellow. Thin with water or washer fluid to make about 3/4 of a jar. Be sure to mix the tube paint in thoroughly. The result should have the consistency of skim milk and the color of butter.To apply, use several very light coats - you should barely be able to see the spray from the airbrush. I typically give 5-10 swipes per car side, repeat on the other sides, and then repeat the whole process until I have the results I want. With light coats I don't need to wait for them to dry. If possible, it's handy to have a witness sample of the color you're starting with so you can see how the fade is progressing.* Wash application. With the airbrush, the fade is pretty uniform. With the last woodchip car, I wanted to see if I could get some additional, less uniform, fading, so I tried making a wash using: ~1 part raw umber, 2 parts zinc white and 3 parts transparent yellow, thinned with washer fluid to the consistency of dirty dishwater. This was applied like any grime wash. Since I only have one example of this wash technique, I don't really know how useful it will end up being, but I like it so far.The proportions in these things are pretty lax. For example, if I'm fading a blue car, I'll use transparent orange instead of yellow to neutralize the blue. With the BN car I was going for some yellowing in particular, so I used more yellow than white in the wash, but I think some yellow is always good to include. With the washes, I think you can start with any grime recipe you like then add some transparent colors as "filler".The main thing is to be patient and build up the effect in light passes (both the airbrush and wash applications). This will give you control and give the finish a nice depth.Ok, this may not be the crisp summary you were hoping for, but I hope it helps.Cheers,Gary
After taking 3 or 4 drops of the paint and diluting it to one full airbrush side jar (1 oz I think) of window washer fluid, I started on this Roudhouse KCS boxcar:9 coats later, I stopped at this:The fade is a tad grainey (suggesting either not a complete dilution, or a bad compressor setting), but I love the color change. Seems to work well too over the reddish brown. Th really good news is that, with about 7.5 oz left in the craft paints, if I do 3 drops to a jar at a time I can fade with this stuff for decades.So gurus, what's my next step on the path to learning?
