I did have a new scope smell after I assembled my GSO dobs. As you probably know the base comes as a flatpack which you screw together. The problem I foresaw is that the cut edges of the particleboard which will not be seen aren't sealed and sooner or later - actually sooner - they will absorb water, swell and disintegrate. So I first painted all bare edges with wood glue to bond them, then applied several coats of exterior paint. Finally, after I assembled it, I sealed every join with a good bead of silastic. The result was a sturdy, durable base which only smelt for a month or two. [Some might say that the optics stink but it's kept me happy
]
PS. Yes I know new car smell but only in a work vehicle. Back in the day I smelt a lot of new text books, some even smelt untouched when I gave them away decades later
