Paint Thinner Transfer

I use a lot of Tamiya paints.

Getting a couple drops of primer out of the bottle can be a pain.

So I got some Pipettes from Hobby Lobby.  I put a couple rubber bands on my bottle of thinner and one is always ready for some work.

Two sizes, big and small, pretty cheap.
 

 

Stick the pippette into the bottle and withdraw a few drops, put it into the paint and return the rest to the bottle.  More control than an eyedropper, the shaft is smaller.
