Spraying soluble matt varnish
I'm getting problems with smear like streaks when brush painting this varnish over dark colours. The bottle I'm using has been mixed very careful and throughly. I've decided I'd like to try airbrushing it to see if that will avoid the streaks. I have good brush and compressor and have bought high grade white spirit to thin it with.
The bottle says thin 1 part thinner to 4 parts varnish. That seems thick to me. Are there any tips regarding the use of this varnish, either to avoid the streaks when brush painting or for the most successful spray application?
Thanks in advance
