Welcome to the forums
I believe a product called "Aircraft Stripper" is what quite a few others have used for the stripping process. Use the "search" function above and read all the discussion/discourse on stripping and polishing.
There's definitely no easy way of doing it, and I don't really think there are any shortcuts if you want it done right - however depending on the condition of your skins, it may take more/less effort than others.
Here's a good thread to start with:
Strip 'n Polish Project Thread ( lots of great tips and links)
