Good vs evil in thinner land

Q: How can I know the lacquer thinner I use is good or bad, weak or strong?
A: First, remember that thinner is tagged to the specific lacquer for which it is formulated. Thus, good thinner for one lacquer may be bad thinner for another. Start by listening to the recommendation of the company that sells the lacquer. They know what is in their lacquer, and thus which solvents should be in the thinner. As for wide spectrum thinners, like those you find at the home store, as much as I hate to say it, the reality is that cheaper thinner is often worse thinner. Typically, it has fewer expensive primary solvents and more cheaper secondary solvents and diluents.
