I’m using an Acrylic clear cover spray because it sprays in very small droplets and on my first pass, if I can remember to hold back, it fogs and settles. I’m able to save 70-80% of the rust dust. Just like using chalks, sealing mutes the colors a tad by nature, so saving as much dust became a necessity.
Krylon ColorMaster, Acrylic Crystal Clear Flat Clear Non-yellowing blah blah blah with Cover Max. If’n ya care.
I’d rather clean the rails than all my wheels after it transfers… The Acrylic is rather hard, so running a modified belt sander once around the layout, works for this lazy old man.
Now if others want to run their trains and clean it for me, I’ll put my feet up and hold off on the sander, (http://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)c’mon over!
