Methylene Dichloride is sold here, in the UK, under the trade name "Plastic Weld".
I keep mine in the fridge, to stop it evaporating.
MEK = Methyl Ethyl Ketone. I don't mind the smell. It's not as bad as Acetone.
Some of the higher Ketones have quite pleasant smells, one has a distinctive 'pear drops' smell.
What bottles do you use to store your DCM?
Would you show an image of the inside of the cap.
What do you tell your spouse when you put the solvent in the fridge? 
I think Weld-On 4 is DCM in the USA.
DCM in Canada can be bought under the name âFast Bondâ.
I do a lot of plastic construction with DCM.
Hobbyists often use this applicator to weld with DCM.
