Thanks for the tips, I will try the residue removal methods, but 
Gasoline?  That's a real big no-no as far as I am concerned. Acetone 
works fine if you use enough of it and I have gone right from Acetone-
toner-removal to transfering again without and polishing. 

Gasoline is nasty stuff - it's bad for the enviroment, it is very easy 
to catch fire, it burns very quickly, and the smell stays around for a 
long time after using.  Acetone on the other hand is very mild by 
comparison - after all, look at the active ingredient in your wife's 
nail polish remover, it's acetone.  I have worked around many 
industrial solvents all my life and I don't mind messing with them, 
but gasoline is just "not good".
