As I research and read to prepare for my model and scenery making, I occasionally run across some items that make some of the current techniques I read about, faster, more controllable and somewhat less messy. There alot of innovations in the commercial and custom paint industry that can be adapted to model and scenery projects.
How about a trigger spray bottle with a fine spray nozzle that can be used at any angle including upside down and still not lose spray quality?
What about when applying the reduced glue solutions to roadbed or scenery? There is a small hand pump pressurized (not trigger) bottle that has an adjustable fan-spray nozzle, like a paint gun. A few pumps and spray a fan pattern of glue across your mountains, rocks or road bed.
Translucent paint masking down to 3/4" for model painting and weathering. Fine detail bendable masking of 1/16"-1/2" that will not shrink back or spring and lift the layer is was laid on.
I thought some folks might be interested in taking a look. http://www.FBS-Online.com
A product line discussion of these and some more effort savers is available on: http://www.coastairbrushtv.com...case-w-Nub_p_73.html
One more Item: I bought 2 books from Amazon that turned out to be great reference and instruction books:
"Airbrushing for Railway Modellers" by George Dent and "The Color Mixing Bible" by Ian Sidaway.
Dent goes into great detail of surface preps by materials, putties and fillers based on the substrate of different metals and various plastics and the application then the preparation for each of the different materials as well as which preparations to stay away from and why. He is also candid about past trial and error experiments of his own. Then the actual priming chapters are equally as detailed. The finish coating, effects, special effects, and final finishing continue with the same depth.
Sidaway did not just write a "recipe book" of paint mixing for color he leaves you with a clear and surprisingly easy to understand foundation of how colors and pigments behave with each other so you can not only use his color recipes but invent your own with an absolute minimum of wasted effort and mistakes when looking for the right shade of old for your model or the right way to fool the eye when blending colors on your scenery to backdrop. This is not a model railroad paint book. It is just easy to adapt the methods and ideas to the modelling application.
Anyhow, did not mean to give an infomercial for these folks. Just some things from other areas we can adapt to our own.
