Anybody using the last record preservative

Back in the early '80s I started using last record preservative now here 40 whatever years later just picked up another bottle because I noticed all my new records have a lot of noise with the exception of a few analog Productions and some Rhino records are pretty quiet but the most have a lot of surface noise long story short picked up a new bottle of last record preservative put it on one of my records and OMG the difference is amazing my system nowadays is way more resolving than it used to be noise floor has dropped into the basement and the musical and the music has jumped to the foreground
