Quoted from Ika:is it that?
I've heard paint thinner is definitely NOT the same thing.
I'm in the same boat as you are, VM&P naptha is not available here in The Netherlands. Products that are available here and -i believe- are the same as VM&P naptha:
Coleman Fuel
Zippo (or another brand) Lighter fluid
Kelfort Cleaner
But please-please correct me if I'm wrong
