I sequence using s35 and never fix my gels or remove the saran after 
drying.  As long as you have enough DNA for template, you should be able 
to read your sequence using this method after an overnight exposure.  
Using baby powder will prevent the gel sticking to your film, if you 
absolutely must not have the saran on the gel.  Just be sure to shake the 
powder evenly over the gel and shake off any excess.
