Is it true records are sealed to look better....

The fact some used Lp sellers spray stuff on the record to shine them up is true.                                          
New? never.

Thanks for the tip on the Spin Clean.  Might have to give that a try. 

There's often dust and paper debris in new records and it certainly won't hurt to clean them.  I have a VPI and sometimes clean new records, but generally don't (mostly due to laziness).  I have at times picked up a bunch of junk on my stylus after playing a new record.

I haven't heard of records stores spraying stuff on used records to hide imperfections.  The local record store I frequent does use a VPI to clean most of their records.  Most of the other shops I've been to, I have to clean their used records before putting them on my table.

SOME vendors will indeed spray something on used records to make the surface look shiny and with fewer imperfections. I have heard thatsome use Armor All! Ack.

New records have nothing on them except mold release agent. I clean all new records before their first spin.

You should also know that there is such a thing as an LP resealing machine. Every Tower Records had one in it's back room; every returned LP was visually inspected, and a disc with no obvious defects (scratches, etc.) was cleaned of fingerprints (with Windex and a paper towel!), reinserted into it's sleeve and cover, and put into a sheet of plastic very similar to the factory one, and sealed. The LP was then put back into the store's racks, and resold to an unsuspecting customer. That an LP is sealed is no absolute guarantee that it is new. One thing that proves a sealed LP is actually factory-fresh is a descriptive sticker on the plastic wrap. Another thing to look for is a seal right on the edge of the cover; the record store resealing machine produced that seal, factory sealing machines didn't.
