In the past I've primarily used Testors Liquid Glue. However, it was not
hot enough for me and I always had gaps in the weld. I tried Tenax but it
left bubbles in the weld that showed as pits when I sanded the seam.
This weekend I tried Ambroid Proweld. It binds quickly and uniformly.
However, I have to be careful not to get any on the surface of the model as
it seems to craze more easily than Testors.
On a relative scale of hot to less hot, would the order be:
Tenax, Ambroid, Testors?
Any shortcomings of Ambroid I should know about before I fall too much in
love with the stuff?

Tenax also requires the cap be screwed on by a gorilla or
it will evaporate. Not cool...

I found on some plastics it never seems to completely
evaporate, leaving the plastic soft.
Have your tried Tamiya Extra Thin Cement? I find it
to be between Testors liquid and Tenax, plus the green cap
bottles have a lovely applicator brush. No, not anything like
the useless brush in the Testors bottle, unless you are thinning
It has become my standard plastic cement. After that, I
use the Testors cement in the black plastic bottle, and then
some Ambroid ProWeld, which is better mannered than Tenax, but
is also very hot.
Tamiya has a thicker plastic cement in an orange(?) topped
bottle. I have some around the clutter somewhere... Hmmm, now
where did it go... mutter, mutter...
Thanks for pointing that out. Today I was going through my "glue drawer"
and found an empty Tenax bottle. I scratched my head and wondered why I
would have an empty bottle in there. Then I couldn't find the half-empty
bottle I thought I had. You solved both mysteries for me.
I'll give the Tamiya glue a try.
Go to your local plexiglas supplier and buy a small can of Weld On #3
I have used this for around 25 years now and it works great on styrene. Also
good for cleaning a paint brush or the airbrush you forgot about and left
full of paint over night.

Testors liquid cement is my favorite - the trick it took me years to
learn was how to properly use clamps. My favorite clamp is the Berna
Assembler. I buy a set every time I see them. Once you get the hang of
properly clamping up an assembly I think the choice of glue may actually
The trick with Testors is to treat it like contact cement - brush both
sides of the join generously, then stick them together and clamp. I
also like to flow a bit along the interior side of the seam for good
measure. If I can get the seam to "mush" a bit, then it's "right".
When I clamp that up and dress it with a Flexi-File when cured, I
usually get a seamless, no putty required join.
Personally, I like the 'keep it simple' approach, so I use MEK. A quart can
from Lowe's is about $9. I haven't had anything fall apart yet. When I
have a joint that I need to lock solid immediately/five minutes ago I use
Zap-a- Gap and accelerator.
I use the same technique as Rufus, get it sloppy with the Testors and
let it mush out the top to be filed, scraped, sanded for a seamless, no
putty bond. Testors and Tamiya are MEK based and Weld on, Tenax, and
Pro Weld (good stuff) are methylene chloride. Tenax evaporates too
quick for my tastes but the other stuff works fine for small welds.
Yeah - seen that. The last bottle of Tenax I bought evaportated on me
before I even got to try it...so it was my last bottle.
Had the same thing happen with a large Alclad purchace. Be warned -
only buy what you plan to use, folks.
