Sorry i have not been online for a while, but im back now...
I was told you can use gasoline as a bonding agent and not ruin the plastic
Anyone heard of this or have tried it

Never heard of that and I don't think I want to try it . When you say "Bonding Agent" do you mean to join polystyrene to polystyrene ? Just go to you local Ace Hardware and buy a quart of M.E.K. for about $10 , it will last you a very long time .

Bonding agent maybe the wrong word. A fellow builer mentioned it..... I never tried it.. was wondering if anyone else has heard of it or tried it.

How about good ol' glue? Gasoline seems a bit hazardous just to join two parts together.

Yeah. I don't know who "they" are but maybe the gasoline fumes is giving them crazy ideas. Great decision to stay away from it for model car use.

Gasoline will not bond polystyrene. Period. Sounds like someone is sniffing glue. If you really want to try it, dip a q-tip in your lawnmower's gas tank (or gas can) then try using it as a "bonding agent".
There are many of other solvents which will work: Like MEK, or acetone, or methylene chloride.
I'm also puzzled about not ruining the plastic? What exactly do you mean? The bonding process melts the plastic - that is normal. What are you trying to accomplish?

Was told it molds and bonds the peices your attaching , suppost to bond peices like concrete .. their words not mine.... permant bond! Well if they want to mess up their models... O wil us zap a gap or something i know wont harm the model or peices.... they build military anyways lol... I'll stick with stufff i know works ....

Wow it was a simple question.... but if Toronto's model king has put the final word in there. Try reading , I wasnt going to try it . but im not the model god you think you are, but your two cents is the be all , end all of what was a simple question.

Now I don't know the person that asked the question or some of the folks responding but I'm sure that is all uncalled for. Even though not the best question, it was a simple one.
I do have to say, over 2000 builds in 53 years? That's more than 30 cars a year. Wish I had that kind of time. I don't think anyone has to "show" what they build to ask a few questions here or any forum. After all, that's what these places are for. I'd figure with your 50+ years experience and your "over 2000 builds" you'd want to help fellow modelers instead if being an arrogant "gentleman" for lack of a better word.
For being a priest, you sure are judgmental, too. Guess its time for confession.
And in advance, say what you'd like. I'm not here as often as some other great members I follow here, but folks like you make it challenging to even want to post any builds here. I can take the constructive comments, but no need to be a a jerk and make comments that make you feel superior just because you've been building at at unbelievable pace.

Seriously, like I said in my previous post, if you are so curious - try it yourself. If you have a gas lawnmower, snow blower, chainsaw, or a weed-wacker (or any other vehicle or tool which uses a gasoline-powered internal-combustion engine) take a Q-tip, dunk it in the tank to get some gasoline on it then try to use it as glue on couple of pieces of polystyrene (styrene). That way you'll be able to see for yourself that it will not work at all. Bonds like cement? Permanent bond? Are you gullible? Someone is really pulling your leg.

I remember my dad putting some cox glow fuel in a cap and brushing it on much like tenax. For filler we used airplane dope (that really stunk) and wood putty.

That might have acted as a solvent. But the castor oil in the same fuel would have also made the joint oily. Dope contains a strong solvent.

I wouldn't try it. Be somewhat embarrassing trying to explain to the ER nurse exactly what I was doing when I set myself on fire with an accelerant !

So you guys use MEK as glue? I have built quite a few but never heard of it. What is it? This ac glue is just not cutting it.

So you guys use MEK as glue? I have built quite a few but never heard of it. What is it? This ac glue is just not cutting it. We are talking about polystyrene (colloquially called "styrene") and or ABS plastic (stuff that injection-molded model kits are made of. MEK is the main ingredient of the good ol' standby Testors Liquid Cement (in a glass bottle). Tamiya liquid cement uses acetone as the main ingredient. Tenex and Ambroid liquid cements are pretty much Methylene Chloride. All of those chemicals can be purchased for fraction of a cost that you pay for the small bottles of the hobby stuff. Acetone and MEK are readily available in hardware store (in the paint thinners section). Methylene Chloride is used as industrial acrylic (Plexiglas) adhesive. I was also able to buy a good size can of it in my well-stocked True Value hardware store. I use Weld-On #3 (on both: acrylic and styrene) but there is a wide range of weld-On adhesives. See www.tapplastics.com/product_info/plastics_information/adhesivesWhen I build models I don't stick with a single adhesive. I use what I think will be the best adhesive for the specific assembly. I use those solvent cements mentioned above, epoxy, CA, contact-cement, etc. They are all very useful in my hobbies.
