Balsarite is great stuff but I gave the hair spray A try this year, anything my wife has in stock at the time. It works pretty good!!! A lot cheaper and doesn't go dry in the can. K2R became hard to find in Calif. so I used all kinds of different tricks to get out the oil, acetone and alcohol mostly. Sometimes it worked and sometimes not. I have looked for K2R here in NV and haven't found any but haven't had any bad fuel soaked planes to recover yet. I may try Mr. Dunckers method A try. Here in NV we can still get Balsarite, in Ca. it is A nono??? Club members that would come here to Vegas would have to smuggle it across the boarder for us.
