I was doing some research but couldn't find a thread on this topic here. Forgive me if this has already been discussed to death. My quart of VM&P Naphtha has pretty much ran out, and I was looking into buying more. When I type "naphtha" into Amazon, I get results for VM&P Naphtha, Mineral Spirits and Paint Thinner.
Examples:
https://www.amazon.com/SUNNYSIDE-CORPORATION-80032-1-Quart-Naphtha/dp/B000LNTWPK/ref=sr_1_12
https://www.amazon.com/Klean-Strip-GKSP94214-Odorless-Mineral-1-Gallon/dp/B000QD7PIQ/ref=sr_1_36

Seems like one quart of VM&P Naphtha costs the same as one gallon of Mineral Spirits.

On the description for the paint thinner, it says "100% mineral spirits" so it would be safe to assume those are synonyms. In researching the distinction between VM&P Naphtha and Mineral Spirits, I found a forum about painting which explained how due to the different composition, Mineral Spirits takes longer to dry (along with other differences, none of which seem particularly relevant here):

I like to use Naphtha as an initial wipe-down of a dirty playfield, and then with magic eraser to help remove dirt ground into ball swirls, planking, etc. For these purposes, should I stick with VM&P, or is Mineral Spirits sufficient?

Isn't the topcoat already worn down considering there are literal indentations filled with dirt ground into the paint (ball swirling and planking)? After magic eraser, I use Novus 2, then wax it

I bought it off Amazon a few years ago with no issue. Is this recent?

Thanks for the tip. How does this compare to Vm&p naphtha?

Went to my local Big 5 sporting good store and they had a gallon for ~$17 with tax of the camp fuel. This is all pretty standard bullshit for CA, I hate this state lol. Don't travel much at all but if I'm ever picking up a game east of me close to the AZ border/in AZ, I will take the extra time to get the illicit material CA has banned

My roommate just told me he's driving to AZ to see his parents, that's clutch. I'm gonna ask him to pick me up a couple gallons of the good stuff and return the camp fuel I just bought.
