CV or Nitro?

Paul,

are there simple ways to distinguish CV from Nitro?

thanks-

No really easy way, especially on older finishes. Nitro will fluoresce under black light to some extent, but this is unreliable though much-touted by some. It also smells bitter and musty when it's sanded, but that's destructive.

Nitro is usually much thinner than CV, with polyester being thickest of all.
