Chemicals? Or what type of Styrene glue is BEST

Depends.  What do you need- do you need quick set- difficult parts do clamp?  Do you need slow set because it will take some time to get parts properly in register?  Is any piece transparent?  Some glues fog transparent parts.  I keep several glues on my benchtop- regular CA, slow setting (gel) CA, very slow set solvent glue, and white glue.  I keep epoxy in a drawer.  Each has it's uses.  Experience willtell you which when.

Hi Don!

       Now, Sir that is good sound advice! But, I always say check the instruction panel. Funny that! Revell's type "S" cement instructions said, always spread a thin layer on both parts and let set a few seconds, then unite the parts for a strong bond.

 Of course Testors Said the same. Duco and Ambroid had the disclaimer ( " Not for use on Plastics") Pactra at that time was just releasing liquid to the marketplace. Boy! That stuff stank! But it worked great!

Remember glue-sniffing?  Ambroid was known as a good sniff by my modeling friends.  Also, some guys would bite off the little glob that develops on the tip of the tube- useful two-for one.  They got the tube ready for the next application and they liked the taste!  I figure I started using Testors Model Airplane glue about 76 years ago!

Yes, Don I do!

       Some of my neighbor's kids got hooked so bad they had to detox. One actually died! I never thought that anything so evil smelling should be inhaled, So I used it with the window in my room wide open even in the Winter and Rain( as long as it wasn't blowing in) to keep the smell down.

     I was surprised later, when A friend in the Navy told me about the " Sniffing Clubs" they had in his neighborhood. He lived in Philadelphia! But the lemony smelling stuff? The worst, stringiest and least dependable of the product. I buy models sometime for parts and I can usually tell which glue was used. If they break apart clean with a little " Fuzzy" looking edge the lemony stuff was used. It seemed to generate Miniscule bubbles even after the join.

     Makes me wonder, Did it ever gas out right? I did get some bottle glue one time. Spilled it on the desk and it ran off on the carpet Monster. It ate a hole in it and destroyed even the barrel of a pen lying there as well!
