Thanks, however please let me elaborate...It has not been banned in Texas but it is a controlled substance and one of several solvents the general population can't find for sale in retail stores in Dallas any longer...even though it is possible the website of Lowe's, Home Depot, ACE, etc may tell you they have it and even go so far as to tell you which aisle it is on. In some of the distant suburbs it may be different, but in Big D it will not be there. I'm told you can get it from chemical suppliers if you have a permit. There is an MEK substitute sold but I'm told it isn't really effective and the reviews give it about 2.6 stars out of 5...plus you must buy a gallon of it for something like $32.
And there are brush cleaners claiming to contain MEK we can buy here, however they don't say it is 100% and I'm pretty certain it has been diluted by something. Toluene is mentioned in the contents section along with "other aromatic solvents."
I tried to get some MEK to thin some fiberglass resin a few months ago and could not find it anywhere.
