The USN is no longer using MEK they are changing their instructions in their manuals to use Methyl Propal Ketone (MPK).

I know this is a quite a bit off topic, so my apologies to the OP.
My Scigrip/Weldon #16 had gone too stiff for me to use. But yesterday I looked up the MSDS and found that MEK is an ingredient. So I picked up some MEK at the local hardware store, and was able to thin the #16 back to a workable consistency.
No apologies needed Cliff. That point is relevant to the question and follows the discussion. Besides, this is Page Two, and per LSC Guidelines the post is fair game for derailing (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-surprised.gif)
Tried both and the MEK works better, I use the acetone to loosen old glues and joints. Best I have found is Model Masters liquid glue, doesn’t dry too fast and melts the plastics together very well, also use Tamiya wicking liquid glue, it come with a little attached brush and wicks into to seam, Bill
The big box stores that are handy in my area only have MEK in gallon cans, besides being more than I will likely use in a life time, the gallon cans that paint and lacquer thinners, acetone, alcohol and others come in are almost impossible to pour out of without spilling.
The small box stores carry more handy sizes …
I have switched to pure MEK over commercial plastic welders. Only because I can buy a life time supply in one can. It works great and does evaporate slowly which I prefer. I have not used acetone. I got a quart at Ace Hardware
I did the same here Devon. (https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-wink.gif)
I only get the little bottles is when I have worn out the brush. For some jobs I like the cap brush and a fine tip artist brush for fine details.
It’s easier to contain the eventual spills in a smaller bottle…(https://www.largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-yell.gif)
Here in the People’s Republic of California, they’ve outlawed MEK. I still have about a half a quart left, but I may try to pick up some more when I’m in Nevada.

Get to work building more models! I go through a quart about once a year. It works best in a squeeze bottle with a metal needle.
