HI ALL brush ????

I have yet to use olls on my models, but for enamels and acrylics I use Red Sable brushes.  They may be a bit spendy at first, but good brushes will last a long time, if you take care of them, that is.  This is what I do:  clean up for enamels, I use mineral spirits then gently roll and stroke the bristles on a paper towel or similar until no paint comes off.  Don't scrub it or you'll damage the bristles.  Then, I'll finish with running water and liquid soap, rinse, roll the bristles on a paper towell to form a point and stand bristles up in a rack or cup.  For acrylics I do the same except substitute water for mineral spirits.  Some may think it's a bit much, but I've used some of the same brushes for more than 10 years.  Also, keep your eyes open for sales at hobby supply houses.

Regards,

Michael B.

Doh!  Yeah, looking at it now, I see that!  In my zeal to be helpful, I didn't read the post carefully enough!

Killjoy,

I think he is asking about paint brushes not an airbrush.

I have never airbrushed oil paints, nor have I heard of anyone doing it.  Acrylics and enamels, sure!  To answer your question, I have a few questions. 

1.  What are you using it for?  Plastic models in 1/35, t-shirts, women's fingernails, etc.

2.  Budget.  This does make a difference.  Expensive is not always, or even necessarily better, but cheap is not good.

3.  Cleaning acrylics can be done with windex.  Enamels usually need lacquer thinner.
