Do the test in a well ventilated area. The lead will come off as a
vapor also.

In the end after some research on the topic, I came to the conclusion that the temperatures did not go high enough to cause the chemical reaction that bound the lead. In other words, it would work with the high temperatures reached in air cooled cylinder heads but apparently not with the lower temp water cooled blocks. At least, that was my conclusion.

Typical abrasive blasting does not work very well due to the shrouding effect of the multiple ground electrodes which tend to shield the ceramic cone.

> Notes on using Decalin RunUp :
> Some white deposits may be seen on the plugs and in the exhaust pipe during use; this is normal with RunUp since the lead in the fuel is being converted to non conductive lead phosphate. When no additive is used, lead oxide is formed. It is lead oxide which causes plugs to misfire due to its partial conductivity shorting out the plug. In addition, lead oxide tends to form in large clumps or clinkers whereas the lead phosphate is crumbly and if any is left behind in the combustion chamber it deposits in even layers.
> Make sure you remove and clean your oxygen sensor every 20 hours to remove these lead phosphate deposits when using Decalin RunUp.
> The dosage of 1/2 ounce per ten gallons of fuel is a minimum. This can be increased to a maximum of 2 ounces per gallon for problem engines.
