I saw a stock finish mentioned in another post and would like to know the proportions to mix it and how its applied.
The finish is spar varnish, boiled linseed oil and turpentine .
Use REAL spar varnish and REAL turp.
Age the turpentine in a shallow dish for at least 24 hours so it can pickup oxygen.
I would mix the varnish 50-50 with the oil then use about 25-50% of that as aged turps.
But I make my own oil by cooking store bought "boiled oil" to reduce its acid content and greatly cut its drying time.
I mix this with Grumbachers Oil Painters Medium III 50/50 and it makes a soft varnish.
But I generally only use this for the top coat.
