Getting A/C system working again

[zukitrek]

Hi Fix. Now that my tune up has been done, now Im moving towards restoring the A/C system in my car. I had taken the car a couple of years ago to an A/C technician and that time it turned out to be having the dryer bad. I bought it about a year ago (also new evaporator and expansion valve) and now I want to install the whole thing. I read somewhere that you need to apply some special refrigerant oil to the evaporator. Can you tell me what do I need to install them properly and then take car to AC shop?

Thanks
