Useful DIY/moulding video, but caution: THE FUMES ARE BAD: only do this outside or with good ventillation.

For modeling work, a far better alternative is super glue and talcum powder. It doesn't produce a chemical reaction (like the baking soda) and the result is closer to styrene in hardness. It's easy to cut, sand and blend into a part.

I've been using this stuff for years.

I've done some experiments with this, mostly as a filler for gaps between parts. Drawback is that it gets really hard, making it more difficult to sand.

Agree, I have been using this recipe for years. And I've left a fill job for months, and it's still as easy to work as something that's newly-set.

Not an issue if you substitute the Talc.

And because it's inert, it doesn't have the potential to weep or discolour over time like the baking soda does.

I've used the baking soda for years and never had a problem. Just don't use it inside the fuselage and close it up right away. Cloudy canopy for sure. I saw a video about using CA and graphite. Not a fan. It didn't harden properly like the baking soda and made a graphite mess on the work bench.

Any adverse reactions if using the talcum powder and CA accelerator?

I have successfully used resin sanding/drilling residue as CA filler, but I am not a fan of the method and rather use 2C putty to fill bigger gaps.

I've tried it.  I made a mess and glued my fingers to things I didn't want to glue them to.
I'll stick with putty or filler.

Oooops,  ;D
Do not condemn the judgement of another because it differs from your own. You may both be wrong.

No; the talc is inert, so the accelerator will only act on the CA.

It only weeps if you use baking powder, as there's other chemicals in it. Baking Soda proper is okay.

Cool, was just wondering if the accelerator was used if it would expand or swell or something. I'll try it out at some point, I have a type of CA that will only set if accelerator is used on it, that's why I asked.

It may not work then, since the accelerator may not make it into the main body of the "putty".

IIRC baking powder is baking soda (bicarbonate of soda) bulked out with flour.
