Counting unrolling the hose and rolling up hose would you believe 15 mins.,when I took the bill by the office he ask howmuch,I was at a lost.I said would a dallor a min. be ok and his mouth like to have dropped to the floor,he said man I cann't afford no dallor a min.,I said will gave me 15 dallors and we'll call it even.He wrote me a check for 45 dallors and said it was worth that much atleast.
If all planes wash up like this one did I think I may just wash a few more,it doesn't take along at all.I rinsed it 3 or 4 times trying to figure out what I was going to charge,on small planes a feller would have to set a price reguardless of the time b/c I want wash nothing for 15 dallors unless you bring it to me.But on large planes I can see where a feller would do ok in making alittle money,the paint is easy cleaned.
O I never use a x-jet nomore and the only thing I used it for was to to blow mud off the farm eqt.
