Upgrading my standard of paint.

[zenrat]

I get my brushes from the art shop rather than the model shop.  They have a better range, they are better quality and they can be cheaper.
Plus the lady in there knows what she is talking about when it comes to painting (OK, canvasses not models but still...).

That's what my local LHS is.  Everything from quilting and textiles stuff to canvas painting supplies, pottery, and all the other crafts lil old ladies like to do.  I love that place. Tons of overpriced malarkey, but, if one knows how to look for it, deals can be found and neat stuff can be found as well amidst all the fall apart and too-costly wares.

For the most part I tend to steer a wide berth around the stuff on the actual model aisle. As far as the brushes go, they're either cheap bunk or way over priced when I can walk 6 aisles down and get my hands on the "real" brushes. Cool thing is, they go on sale quite often and even when they don't, I can buy one at a time at 40% off so they wind up not being that expensive. There were a few times where I almost bought one or two.... in hind sight I should have and maybe I wouldn't have dealt with so much frustration from these janky "shedding" brushes.

I have a couple of 000 & 0000 brushes that I use for extra-super-nano-fine painting. (Them & a bloody good magnifier/light. )

What's the deal with the numbering system anyway? Any correlation to some type of established set of measurements or... what? 

[Old Wombat]

Yes.

Problem solved!!!

WRT the flat brushes, there is a variety which has slightly curved-in bristle ends, called apparently a Bright, or Filbert.
I've grabbed a 1/8" one for cam schemes, or the edges of them, as it's easier to make curves with than a straight-ended brush.

As far the 00 and 0 brushes.. well, that's my problem! I'm finding even these to be too large for certain things like detailing pilots and cockpit panels. I've gotten a little bit better at it by adding only tiny amounts of paint to the very end of the brush but still find them lacking at times.

The smaller the brush, the better quality you need in order to get good results. But for switches and dials I still use a toothpick.
