Re: Kerosene fuel as paint thinner
If kerosene is so much cheaper, don't you think that paint manufacturer would just use it and pocket the differece?
The naptha is there for a reason - it's a more powerful solvent.
I can tell you from experience cleaning bottom paint off of paint brushes that mineral spirits does NOT fully clean the brush. I need to use the naptha-containing brushing thinner to dissolve all the paint off the brush.
You can experiment all you want, but you'll just be reinventing the wheel. The paint manufacturer spent thousands of hours of R&D time coming up with the right composition.
If you really want to save money by making your own thinner, at the very least you should duplicate the composition that the mfg reports on the MSDS. Then you'll have to buy some naptha and blend it into the kerosene at the 25% level.
