Nice first try! It's been a long time since I've used the toothbrush trick, but I think thinning the paint will produce smaller specs. Also less paint on the brush is best, use multiple passes to build up density.
Rob - amazing work IMO.But I can control that right? Less paint on the toothbrush. Greater distance away. Etcetera. Tips...?
Lastly, Tamiya is a solvent-based acrylic, also try using Water based paints, like Floquil R/R colors - or something like regular ol house paint.
And remember to - Have FUN!
I've got a rattle-can black that gives pretty consisent and just about perfect results. I don't have a really good white though.vaderdarth is Right! The Spray test does look better - Size-wise, but the issue of Consistency & Permanence (re: Rattlecans) gives me a big Pause for Concern!
