True , i'v being using it all day , although im not overly fond of the orange D-limonene smell up close . Another component is mineral spirit or naptha on the american data sheet , this is close as makes no difference to odourless white spirit which is itself very versatile . I recently picked up ultrapac to use on this cremewhite stairs/landing i was facing with numerous draft marks , UR would not shift the worst ones on its own , spraying odorless white spirit after worked though .
