Oil washes

Dadfad,

1) You can apply oil washes using a paint brush. I personally prefer pointed brushes as they limit the area where oils are applied. Allow the tip to touch the panel line and the oil will creep by capillary action.

2) Oil washes go very well with acrylics.

3) Depending on the consistency of your wash, you can remove the excess by wiping it off with tissue or a soft cloth anywhere between 1 to 3 minutes after the oil wash is applied.

Hope this helps.

What do i use to thin the oil wash?

You can use ordinary paint thinner. Mix at a ratio of about 20% oils and 80% thinner, but the ratio will depend on the degee of weathering you desire. Add in more thinner for a more subtle wash especially on light colors.

A word of warning though, the mixture described above will affect enamel finishes, so wiping off the oils is impossible without rubbing off some paint as well.

The excess comes off great if you dip your brush into clean thinner, then sop up the excess with it. The excess will gravitate right onto your brush. Make sure the excess is where you don't want it to be on the surface, though.
