I got this body and pickguard for Christmas. A builder I know made it for me. It is a contoured Mustang body shape with Jazzmaster pickup, bridge, and tremolo routes. It is full scale and poplar. (Old wood Mustangs were once made of.) It is a one piece body.

The body's builder also sent me Z Poxy to grain fill and seal the body. The stuff is very nice because you don't have to be perfect when you mix it. Get as close as you can though so it will dry. Just use a small piece of hard plastic like a credit card or spatula to spread it on thin and even.

Sand it nice and smooth when you are done with fine sand paper. The smoother you get it, the smoother your paint coats will go on.
