peelaway 1

I've got a front door that's covered in lead based paint. There were multiple layers. I used Peelaway 1 but there is quite a bit of residue left and bits where the last layer of paint hasn't shifted. I've attached some before and after pics. What next? Should I add another layer of the stuff...

Hey all, has anyone found a good way to remove dried up peelaway 1 stripper from wood? I have to sand it off and its real tough like plaster :-\ is it ok to paint over this stuff if traces are left on? It's pretty much impenetrable to water.
