my 2cents:) no worth mutch i guess....something like bio 
degradable..simple green?
soak then wash off with water? rebake in the sun..sucks tho if you 
live in  the artic.
i can only set stuff maybe 3 months in the year,,by the sun.it is natural.
the rest of the time it is artifical baking and hoping i did it right.
but then i have a real job and it takes presenendance.

my spelling checker is on the blink...so srry  if mispelled...


ps. Dr.R,,
i will email ya about the flybacks and maybe me and you would chat on 
fone a bit?
nothing in a rush but it would be nice a day this week....or next week...tim

Dr.
To clean such oils off of the secondary coil what should one use not
to damage the urethane coating?
