383-A disassembly help needed

I have a Bersa 383-A with the nickle finish and I need some help. the finish has gotten old and has some scratches and a few dull and bright spots. I have decided that I am going to take it out to the garage and glass bead blast it to give it a nice uniform satin finish but here is where I need help. in order to blast the frame and slide without getting glass & sand everywhere in the internals (would be a "BAD" thing) I need to do a complete (armorers) disassemble. I have done a full disassemble on every gun I own except this one. there is a profound lack of information available on tis particular model. can anyone here provide me with or guide me to a tutorial or video on how to strip the 383-A down to the bare bones. and of course how to put it back together again...
