Send me a private message and I will help you. You need to see if you can find a Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) for the Texaco product you have. See if you can find a part number on the bucket which may help.

So, to answer your question.... mineral spirits evaporates very, very slowly (days/weeks) & is not the best solvent for some types of undercoating/paint. Yes, "eventually" the mineral spirits will evaporate & leave just the undercoating.


Almost all paint thinnners (aka undercoating thinners) are flammable.
