Why don't you just go to AutoZone, O'reilley's or NAPA and BUY IT along with the resin If you don't know where to buy fiberglass materials I have to wonder if you know what you are doing with it once you get it. It's not as easy as you may think it is to work with if you have never done it and ONCE you make a MESS. it's almost impossible to un-do it.
I WOULD NEVER USE COPPER.HAS VERY POOR WATER FLOW AND IS REALLY EXSPENSIVE. I SUGGEST YOU USE PEX TUBING IT IS LEAGAL TO USE ANYWHERE IN US AND IS A THRID THE PRICE OF COPPER. AND YES 1/2 INCH IS A GOOD FEED SUPPLY.
depending on your state a wall thickness of type L (since copper pipe comes in lettered thickness G thru K and DWV for drain) you cannot go wrong this is the standard thickness for most areas. where i live type M is the standard which is slightly thinner wall than L. K is used mainly for underground.
