CV finish question

[1OUfan]

I'm sure Paul knows the answer, but I'll just ask generally----
When did Ric start using CV as their finish?
Thanks---

I've heard the fifties guitars were nitrocellulose. So I'm guessing early sixties?

From this very forum. A question/answer topic with Peter and John Hall. JH's answer to finishes.

"Contrary to what you say, the clear coat has varied very little. Indeed, there have been UV filtering additives to stop yellowing, but mostly a reduction of the VOC's, but the chemistry and family of finish has not changed. Perhaps you're referring to the urban legend about nitrocellulose? Our use of nitrocellulose was stopped in the late 1950's, replaced by the current conversion varnish system. Originally it was based on the Fuller system, later the Sherwin-Williams base formulation. More recently, Lawrence-McFadden has supplied raw material. (We blend the base material with other components to bring it up to our specs.) Some nitro was used in sealer coats for part of one year in the early 80's, mainly as part of a test, but other than that has NOT been used for a very long time."

There you go.

1958, to be precise.
