I know in 68 Fender changed to poly or a blend there of. I have been looking to buy a mid 70's strat. Most are natural, or ugly SB, I finally found an original 1976 Blonde strat. Very cool color. If you take the pick guard off, the blonde is a whole lot lighter. It has aged like nitro. I did'nt think poly turned gold. My question is, did Fender shoot poly on natural and SB strats as a norm , but Olympic White, blonde was clearcoated with nitro? Is this a possibility? Any ideas? Thanks, scarb Here's a picture.
