Straight MEK will work, but it is SLOW.
If you can't find "Same Stuff" plain Dope Thinner works better than MEK.
Plastruct BONDENE is the same as Tenax 7R (MeCl), but Plastruct plastic welder is NOT; that stuff is just MEK like Testors liquid cement now is. Too slow.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
