One other thing... there is some shrinkage with Tamiya's putty. Might be common with othe fillers as well, but Tamiya's shrinks about 20% (my guess). Best to overfill a bit or build up with several applications curing inbetween if it needs to be thick.

I got a small bottle of acetone at Dollarama, that is our Dollar Store chain here in Southern Ontario. It is the traditional nail polish remover, it is also very good for getting varnish type Coatings off of copper wire so that it can be soldered👍

MEK is quite potent and a healt hazard. Safer choice is acetone which is safer (still be careful!). Acetone can be found in many store as nail polish remover (look for 100% acetone). Also low cost.

Work very well with styrene and ABS. I 3D print with ABS and cement it to styrene.

Acetone is very thin (much thinner than model cement) and can be applied various ways. I often use small brushes, tweezers, and even syringes.

I agree with Bobby. I grew up in the Squadron Green Putty. But, it is no longer available so the Tamiya white putty has taken over the market. Vallejo makes a plastic putty that is catching on in a big way. My son swears by it. It has a more liquid consistency and is easy to spread in tight spots. The war game folks love it.

I agree with Tamiya putty but there was a product which is now hard to get called Squadron putty, this product was very good as a plastic putty. There are a few other options which you could try out on some scrap. You could make your own putty by dissolving styrene in MEK I have used this to good effect especially with 3d printed parts. I use a runny version of this as my glue welds styrene very well. Also a friend uses baking soda with super glue. He swears by this.

Hope this helps

Sorry I can't help as I have never used this product. Cheers Ian

I am with Lew! Tamiya white putty is what I use!
👍

I find that Tamiya putty works very well sticking (more like fusing) to styrene as well to fingers. Sands very well. I have been using this for many years.

Hi Merchant 67,
Balsa filler deffo no! You need something finer than that or P38 and above all something chemically designed to bond with the plastic.
For styrene/polystyrene I use Plastic Putty.
Here in Germany I use the Revell version, but there are many others.
In UK for example from Deluxe Materials. See attached links.
Cheers, Doug😎
