Hi,
New to 1/35th scale models although I have been building and painting 15 & 20mm wargame models for sometime. I have read several articles that say to use an oil paint wash over acrylics. All my experience with washes were acrylic paint mixed with water and a drop of future floor wax. Whats the purpose of using the oil?

If you have done acrylic washes and feel comfortable with that method, you may want to stick with it.

The nice thing about oil paint wahses is that they can be manipulated a bit more than acrylics. Just to clarify, we are talking here about making a wash with artists oil paint, usually thinned with mineral spirits. It has a very low surface tension and flows easily into engraved lies and around raised surface details. It works nicely on top of acrylics because it usully will not attack or soften the acrylic base coat. I have used oil washes on enamel base coats, but sometimes the wash is a little too "hot" and will lift the enamel.

Welcome to Armorama! Hope I've helped answer your question.

Oil washes attak Model Master enamels. Be careful. With humbrol enamels it works fine.
