What are the effects of using Turpentine Substitute?
Turpentine Substitute should never be used with oil colour. It is a cheap DIY solvent, which when used, runs the risk of discolouration and non-drying of the oil colour. Its only acceptable use for artists is for cleaning brushes. The number of tacky paint films resulting from old turps or cheap DIY solvents are second only to the number of problems with sinking.
