RE: Linseed oil impacts??

Ther are several variations on the theme of non-diesel release agents
for beds of asphalt trucks including Thermal Slide, Slide Guard, and
Chemstation. I don't know all the ingredients but Potassium Hydroxide
(KOH) seems to be a popular one. 

A little seems to go a long way as 2-3 55-gal. drums of release agent,
mixed ~40 or more to 1 with water, will last a paving season (May to
Early November) for a plant in Colorado.
