I am using a Sure Shot sprayer. I have put 20 ounces in a glass jar and put it in a microwave for about 1 1/2 minutes, was luke warm, and then stirred it up and put it in the sprayer with 110 psi of air. The FF came out in a couple of streams instead of a spray. So my question is how much vegetable oil would you mix in with the FF. Would you heat up the vegetable oil? Is there anything else that you could use for thinning. Thanks, Bernie.
