Been running into the same issue where I live. A lot of commonly used products that are mentioned on the forum just go by a different name but are the same thing. I've been searching high and low for the Dutch alternative of Naptha. Turns out it's the same thing as "wasbenzine", which you can even buy at the local grocery store.
Perhaps its a good idea to make a thread to summarize these alternative product names for commonly used products, and where you can get them, per country. You don't want people to ruin their playfield with some heavy solvent because they thought it was the same thing as naptha.
