Yes, Linseed Oil. I Used To Use

So Many People Say Painting Is Fun. I Don't Find It Fun At All. It's Hard Work For Me.

I Believe That The Great Painters With Their Intellect As Master Have Attempted To Force This Unwilling Medium Of Paint And Canvas Into A Record Of Their Emotions.

I Trust Winsor And Newton And I Paint Directly Upon It.

It's To Paint Directly On The Canvas Without Any Funny Business, As It Were, And I Use Almost Pure Turpentine To Start With, Adding Oil As I Go Along Until The Medium Becomes Pure Oil. I Use As Little Oil As I Can Possibly Help, And That's My Method.

The Only Real Influence I've Ever Had Was Myself.
